Polymicrogyria (PMG) and periventricular nodular heterotopia (PNH) are two developmental brain malformations that have been described independently in multiple syndromes. Clinically, they present with epilepsy and developmental handicaps in both children and adults. Here we describe their occurrence together as the two major findings in a group of at least three cortical malformation syndromes. We identified 30 patients as having both PNH and PMG on brain imaging, reviewed clinical data and brain imaging studies (or neuropathology summary) for all, and performed mutation analysis of FLNA in nine patients. The group was divided into three subtypes based on brain imaging findings. The frontal-perisylvian PNH-PMG subtype included eight patients (seven males and one female) between 2 days and 10 years of age. It was characterized by PNH lining the lateral body and frontal horns of the lateral ventricles and by PMG most severe in the posterior frontal and perisylvian areas, occasionally with ...

CONTEXT: Acute pancreatitis in ectopic pancreatic tissue is an uncommon cause of acute abdominal pain and can be difficult to diagnose on imaging. Our aim is to raise awareness and aid in the diagnosis of this entity by highlighting helpful dynamic contrast-enhanced MRI imaging findings. CASE REPORT: We report a 51-year-old man with acute onset epigastric pain presented to ER. With the presence of elevated serum lipase, the clinical diagnosis of acute pancreatitis was made. Contrast enhanced CT demonstrated normal pancreas and a focal mass at the duodenojejunal flexure, mimicked a neoplasm. Subsequent dynamic contrast enhanced MR images demonstrated enhancement pattern of the lesion similar to the native pancreatic tissue enhancement, a finding raised the possibility of acute pancreatitis in ectopic pancreatic tissue, but tumor was not excluded. Finally, patient undergone surgical bowel resection including the suspected mass that was proved as an ectopic pancreatic tissue on microscopic examination.

The butterfly effect is defined as the sensitive dependence on initial conditions, where a small change at one place in a deterministic nonlinear system can result in large differences to a later state. In medicine, the identification of a rare disease or a genetic mutation may provide insights that spread well beyond the initial discovery.. And in genetics, scientists are learning just how widespread the effects are for mutations in one gene: filaminA (FLNA).. FLNA is a common cause of periventricular nodular heterotopia (PVNH), a disorder of neuronal migration during brain development. The syndrome was first described by the late Peter Huttenlocher, MD, and the gene was identified by Christopher Walsh, MD, PhD, of Boston Childrens Hospital.. In normal brain development, neurons form in the periventricular region, located around fluid-filled ventricles near the brains center, then migrate outward to form six onion-like layers. In PVNH, some neurons fail to migrate to their proper position ...

Bulla 2 1 Institute for Maternal and Child Health, IRCCS Burlo Garofolo, Trieste, Italy 2 Department of Life Sciences, University of Trieste, Trieste, Italy E-mail address: [email protected] (C. Agostinis). Background: The complement (C) system is one of the major components of humoral innate immunity, acting as the first lines of defence against microbes. The principal roles of C system are the opsonization and lysis of pathogens, but new roles in inflammatory and immunological processes are emerging. It is involved in numerous inflammatory diseases, such as SLE, PNH and endometriosis (EM). Several groups have been demonstrated that the glandular epithelial cells found in endometriotic implants produce and secrete the C component C3. The aim ...

CONCLUSIONS: We report the clinical and mutation spectrum as well as MR imaging for a large cohort of 47 patients with Filamin A associated PVNH including two adult males. Our data are reassuring in regard to psychomotor and cognitive development, which is within normal range for the majority of patients. However, a concerning median diagnostic latency of 17 to 20 years was noted between seizure onset and the genetic diagnosis, intensely delaying appropriate medical surveillance for potentially life threatening cardiovascular complications as well as genetic risk assessment and counseling prior to family planning for this X-linked dominant inherited disorder with high perinatal lethality in hemizygous males. ...

Since the observation that malformed brain structure is associated with intractable forms of epilepsy, there has been a great deal of interest in trying to understand the function of dysplastic neurons. Here we performed experiments to investigate the influence of GABAergic inhibition on hippocampal heterotopic neurons in an animal model of malformation-associated epilepsy, e.g., rats exposed to MAM in utero. Our main findings in these animals include the following: (1) an alteration in the decay kinetics of evoked and spontaneous IPSCs recorded on heterotopic neurons, (2) normal inhibitory responses for heterotopic neurons after exogenous GABA application, (3) an inability to alter IPSC decay kinetics when heterotopic neurons are exposed to GABA transport inhibitors, and (4) a low level of GAT expression in heterotopic cell regions. Together, these results suggest altered inhibitory synaptic function at heterotopic synapses in the MAM model.. Abnormal electrical discharges, the hallmark of ...

Aphanitic Singularity [abstrakt Alisa Andrasek + Netochka Nezvanova All possible branches are real (Borges, J.L. The Garden of Forking Paths) Gardens were always optimistic reflections of the world, the liminal spaces between the known and unknown, matter and aether. Foucault describes gardens as the oldest form of heterotopias, a microcosm of species, the smallest parcel of the world in its totality: The heterotopia is capable of juxtaposing in a single real place several spaces, several sites that are in themselves incompatible ... the oldest example of these heterotopias that take the form of contradictory sites is the garden.

Most of us are born with two ureters, one to drain the urine from each kidney into the bladder. But some babies are born with 2 ureters that drain a single kidney. In these cases, one ureter drains the upper part of the kidney and the second ureter drains the lower part of the kidney. As long as they both enter the bladder, this extra ureter is usually not a problem.

Periventricular nodular heterotopia (PNH) is a disorder of cortical development [1]. PNH is a term used to describe the collections of neurons lining the lateral ventricles that have failed to migrate normally to form the cerebral cortex [1]. It is a clinically and genetically heterogeneous group of disorders [2]. Mutations in the filamin A gene (FLNA) result in an X-linked dominant form of this disorder [3]. Mutations in FLNA leading to protein truncation are the predominant cause of the PNH phenotype [2, 4]. Most affected females present with seizures and normal to mildly impaired cognitive function [2, 5]. FLNA-associated PNH may also be associated with other cerebral malformations as well as extra-cerebral features [6]. The condition typically results in prenatal lethality or a more severe phenotype in males although paternal transmission has been documented in the literature [2, 7-9].. Mutations in FLNA are associated with a wide spectrum of disorders including the otopalatodigital syndrome ...

Filamin A is an important gene involved in the development of the brain, heart, connective tissue and blood vessels. A case is presented illustrating the challenge in recognising patients with filamin A mutations. The patient, a 71-year-old woman, was known to have heart valve disease and bilateral periventricular nodular heterotopia when she died of a subarachnoid haemorrhage. Autopsy showed typical cerebral bilateral periventricular heterotopia and vascular abnormalities. Postmortally, the diagnosis of a filamin A mutation was confirmed. Recognition during life may prevent cardiovascular problems and provide possibilities for genetic counselling. ...

Heterotopic pancreas is an uncommon developmental anomaly of upper gastrointestinal tract. Heterotopic pancreas tissue is very rarely found in ileum. Intussusception in children is usually idiopathic, but definitive aetiology can be established in 90% of adult cases. We are reporting a case of pancreatic heterotopia presenting as a lead point of ileo-ileal intussusception in a 1year 3month year old boy.

A nine year old male castrated Siberian Husky presented with a history of cyclic fever, anorexia and lethargy of one year in duration, along with chronic urinary tract infections and urinary incontinence. Initial diagnostics revealed a progressive pneumonia, an intramural ectopic left ureter, and left-sided hydroureter and hydronephrosis. The ectopic ureter was corrected via a ureteral transposition, and the animal recovered well from the procedure. Ectopic ureters are a common cause of urinary incontinence since birth or weaning. They may be unilateral or bilateral, and intramural or extramural. The cause of this abnormality is debated, but it is likely dependant on genetic factors. Ectopic ureters are often associated with other structural or functional abnormalities, which should be identified prior to surgery. Surgical correction may be accomplished via a neoureterostomy and urethral / trigone reconstruction, a ureter transposition, or a nephroureterectomy ...

The carcinoids are a neuroendocrine group of tumors, arising from Kulchitsky cells. They can arise from along the gastrointestinal tract or the bronchial mucosa. The tumor can Release serotonin may produce carcinoid syndrome (flushing, diarrhea, and wheezing). Carcinoid was defined in 1907 by Oberndorfer but is now more relevantly named as the neuroendocrine tumor [2]. The origin of neuroendocrine tumors of the mediastinum is either from thymus or from the ectopic neuroectodermal tissue. Rosai and Higa are credited with the first description of such tumors in the thymic region [5]. There is the marginal relevance of the precise distinction between thymic and mediastinal carcinoids [6]. However, few cases of posterior mediastinal carcinoid tumor reported so far have been attributed to ectopic thymic tissue [7]. Clinically, patients may be asymptomatic or may present with symptoms of compression of the mediastinal structures [7]. As but our patient present with dry a cough and dyspnea since six ...

Meckels Diverticulum What is Meckels diverticulum? Meckels diverticulum is a small pouch in the wall of the intestine, near the junction of the small and large intestines. The pouch is a remnant of tissue from the prenatal development of the digestive system. It is not made of the same type of tissue as the small intestine, but, instead, is made of the type of tissue found in the stomach or the pancreas. The tissue in Meckels diverticulum produces acid, just as the tissue of the stomach does. The in...

A few mutations in the ARFGEF2 gene have been identified in individuals with periventricular heterotopia. These mutations may interfere with vesicle trafficking, which is important in controlling cell migration during the development of the brain. Nerve cells (neurons) that do not migrate properly during development form clumps around fluid-filled cavities (ventricles) near the center of the brain, resulting in the signs and symptoms of periventricular heterotopia.. Mutations in the ARFGEF2 gene may also result in weakening of the attachments (adhesion) between cells that form the lining of the ventricles, by impairing the trafficking of the molecules needed for this adhesion. A weakened ventricular lining could allow some neurons to form clumps around the ventricles while others migrate normally to the exterior of the brain, as seen in periventricular heterotopia. ...

We read with interest the report by Mitchell et al1 of 4 cases of ectopic posterior pituitary lobe and periventricular heterotopia on MR imaging studies. The authors suggested that ectopic posterior pituitary lobe with growth hormone deficiency is part of a spectrum associated with septo-optic dysplasia and concluded that the coexistence of periventricular heterotopia dysplasia implies a common underlying genetic mechanism. Further, in 1 case, they found the presence of a heterozygous HESX1 mutation, a gene associated with ectopic posterior pituitary lobe and septo-optic dysplasia, and suggested that this gene is important in the development of both ectopic posterior pituitary lobe and periventricular heterotopia..

Meckels diverticulum is the most common developmental anomaly of the gastrointestinal tract, affecting 1-4% of the general population. It is usually an incidental finding during laparotomy for other causes; occasional complications are bleeding, obstruction, diverticulitis and perforation. Up to 60% of Meckels diverticula harbor heterotopic mucosa (mostly gastric or pancreatic), neoplastic degeneration occurs in 1-5% of cases. We report herein a case of obscure gastrointestinal bleeding in a 25-years-old man, due to a double Meckels diverticulum, both located into jejunum and ileum, harboring ectopic gastric mucosa, diagnosed by a small bowel double contrast enema and managed laparoscopically with a tangential resection. To the best of our knowledge this is an unfrequent case of such a variant of Meckels diverticulum with ectopic gastric mucosa diagnosed by double contrast enema.. ...

Meckels scan: A Meckels scan involves the administration of 99mtechnetium pertechnetate followed by scintigraphy. The scan identifies areas of gastric mucosa and a will detect a Meckels diverticulum if it has ectopic gastric mucosa.. Approximately half of all Meckels diverticulum do not have gastric mucosa and thus do not cause bleeding and cannot be detected by a Meckels scan. Most are asymptomatic although some can cause recurrent obstruction. A Meckels diverticulum which does not have gastric mucosa may be detected on cross-sectional imaging, although only with a high degree of suspicion. A Meckels diverticulum without gastric mucosa is often an incidental finding at the time of laparotomy, laparoscopy or autopsy.. Laboratory values are significant for a low hemoglobin, which can often be below 8 and is caused by acute hemorrhage. Acute hemorrhage causes vasoconstriction which often decreases the bleeding and helps to stabilize the patient while workup can be performed.. ...

BACKGROUND: Intestinal intussusception is the most frequent cause of small bowel obstruction in children between the ages of 2 months and 5 years and often remains idiopathic in etiology, even after surgery. On microscopic examination, in intussusception normal mucosa is noted but in a few cases heterotopic tissue can be seen. Heterotopic gastric mucosa in the small intestine is extremely rare except for its occurrence in remnants of Meckels diverticulum. In view of the rarity of this condition, we report a case of ectopic gastric mucosa in the small intestine that was not associated with remnants of vitelline duct ...

Ectopy of the ureters is a congenital malformation in which the termination of one or both ureters is elsewhere than in the trigone area of the bladder. It is the most common cause of urinary incontinence in young dogs. In dogs with ectopic ureters the ureteric bud arises too far ... read more cranially on the mesonephric duct. This lengthens the distance for the bud to reach the bladder, and the ureters will open more caudally in the urinary tract. Diagnosis can be made with radiographic contrast studies, ultrasound, cystoscopy and urethroscopy and computed tomography (CT). There are several techniques described for surgical treatment, but the aim is repositioning of the ureteral orifices into the bladder lumen. Ectopic ureters are more commonly diagnosed in females. It is considered to be hereditary because of the increased prevalence in some breeds, for example in the Labrador retriever. Identification of the involved genes can help with early diagnosis and screening of dogs for breeding. In ...

The clinical presentation, imaging, treatment, and pathology of a case of neuroglial heterotopia in the nasopharynx causing airway obstruction in a newborn are reported from Columbus Childrens Hospital, OH. MRI and CT showed a cystic mass filling the nasopharynx with a midline bony defect in the sphenoid bone above the clivus. Posterior nasal endoscopy visualized the cystic lesion prior to surgical removal. Connection with CSF and subarachnoid space was excluded. At 6-month follow-up, developmental miletones were normal, and repeat CT showed no evidence of recurrence of the mass. Histopathology of the lesion showed choroid plexus, glial, and respiratory-like epithelial cells. [1]. COMMENT. Reviewing the literature, the authors found reports of 30 cases of pharyngeal neuroglial heterotopia. Both CT and MRI are recommended in the assessment of nasopharyngeal masses. CT visualizes any bony deformities of the skull base, and MRI detects intracranial connections through the skull defect. ...

Schizencephaly (from Greek skhizein, meaning to split, and enkephalos, meaning brain) is a rare birth defect characterized by abnormal clefts lined with grey matter that form the ependyma of the cerebral ventricles to the pia mater. These clefts can occur bilaterally or unilaterally. Common clinical features of this malformation include epilepsy, motor deficits, and psychomotor retardation. Schizencephaly can be distinguished from porencephaly by the fact that in schizencephaly the fluid-filled component, if present, is entirely lined by heterotopic grey matter while a porencephalic cyst is lined mostly by white matter. Individuals with clefts in both hemispheres, or bilateral clefts, are often developmentally delayed and have delayed speech and language skills and corticospinal dysfunction. Individuals with smaller, unilateral clefts (clefts in one hemisphere) may be weak or paralyzed on one side of the body and may have average or near-average intelligence. Patients with schizencephaly may ...

The normal canine thyroid gland consists of a right lobe, which extends from the caudal border of the cricoid cartilage of the larynx to the level of the 5th tracheal ring, and a slightly more caudal left lobe, which extends from the level of the 3rd to that of the 8th tracheal ring[2]. Infrequently, an isthmus located ventral to the trachea connects the lobes. The right lobe is in close proximity to the common carotid artery, the internal jugular vein, and the vagosympathetic trunk; the left lobe is in close proximity to the caudal laryngeal nerve and the esophagus. Ectopic thyroid tissue occurs frequently, located intrathoracically in the heart and heart base[3]. The parathyroid glands are closely associated with the thyroid gland, with a parathyroid gland frequently being located at the cranial surface of each thyroid lobe, and the second parathyroid gland frequently being embedded within the thyroid tissue. Lymph drains from the thyroid gland in both cranial and caudal directions[4]. Lymph ...

Meckels diverticulum is a small pouch in the wall of the intestine, near the junction of the small and large intestines. The pouch is a remnant of tissue from the prenatal development of the digestive system. It is not made of the same type of tissue as the small intestine, but instead, is made of the type of tissue found in the stomach or the pancreas.. The tissue in Meckels diverticulum can produce acid, just as the tissue of the stomach does. The intestinal lining is sensitive to being in contact with acid, and eventually an ulcer can form. The ulcer can perforate (rupture), causing waste products from the intestine to leak into the abdomen. A serious abdominal infection called peritonitis can result. The intestine can also become obstructed (blocked) by Meckels diverticulum.. ...

Fifty-eight human thyroid glands obtained at autopsy from fetuses with proven retrosternal thymus were systematically studied for the presence of intrathyroidal thymic tissue. The latter was found in one thyroid lobe in each of three fetuses (5.1%). It was located in a subcapsular position in two cases (3.4%) and lying deep in thyroid tissue in one (1.7%). Our findings would support a IV-V pharyngeal pouch origin for some accessory thymic tissue and would provide an explanation of the histogenesis of intrathyroid thymomas.

This study aimed to investigate the therapeutic potential of hydrogen-rich saline on pancreatic ischemia/reperfusion (I/R) injury in rats. Eighty heterotopic pancreas transplantations (HPT) were performed in syngenic rats. The receptors were randomized blindly into the following three groups: the HPT group and two groups that underwent transplantation and administration of hydrogen-rich saline (HS, ,0.6 mM, 6 mL/kg) or normal saline (NS, 6 mL/kg) via the tail vein at the beginning of reperfusion (HPT + HS group, HPT + NS group). Samples from the pancreas and blood were taken at 12 hours after reperfusion. The protective effects of hydrogen-rich saline against I/R injury were evaluated by determining the changes in histopathology and measuring serological parameters, oxidative stress-associated molecules, and proinflammatory cytokines. Administration of hydrogen-rich saline produced notable protection against pancreatic I/R injury in rats. Histopathological improvements and recovery of impaired ...

Center for Family Planning and Human Reproduction, Krivoy Rog The main theories of the pathogenesis of endometriosis are described. A modern approach is presented concerning the eutopic endometrium of patients with endometriosis and endometrioid heterotopia, including changes in the expression of inducers of adhesion, invasion, angiogenesis, hormonal inducers, receptivity and inducers of immunity. Differences in healthy endometrium, endometrium of patients with endometriosis and endometrioid heterotopia have been determined. These studies contribute to increasing knowledge of the pathogenesis of endometriosis, the timely identification of possible therapeutic targets and, in addition, realize the effectiveness of methods for early diagnosis and prediction of the course of this pathology. Key words: endometriosis, ectopic endometrium, hormonal inducers, eutopic endometrium, receptivity. REFERENCES 1. Margarit L, Taylor A, Roberts MH, Hopkins L, Davies C, Brenton AG et al. 2010.

Klippel-Feil Syndrome is characterized by congenital fusion of two or more cervical vertebrae. There may be other spinal problems such as spina bifida and scoliosis. Abnormalities of other organs, such as the kidney, heart or lungs can also be present. Features include a short neck, low hairline at the back of the head and restricted mobility of the upper spine.

From the question on page 395 Clinical and CT findings suggested a differential diagnosis between pleural metastasis and splenosis. Histopathology revealed normal splenic tissue, allowing the diagnosis of pleural splenosis.. Thoracic splenosis (TS) is a benign acquired condition involving the autotransplantation of splenic tissue into the pleural cavity. It frequently results from left upper abdominal trauma with concomitant splenic damage and left diaphragmatic tear. Splenic tissue gains access to the left pleural space and derives its blood supply from the pleura, chest wall or diaphragm. TS is usually asymptomatic and found incidentally by imaging examinations performed for other reasons. It rarely causes chest pain or haemoptysis.1-5 The average interval between trauma and TS diagnosis is ∼20 years.. Splenic implants are sessile or pedunculated reddish-blue nodules of normal splenic tissue with diameters ranging from a few millimetres to several centimetres.2 They may occur on the parietal ...

Results Non-neoplastic acinar cells were stained diffusely, but epithelial cells of the pancreatic duct and the islets of Langerhans were not stained. In pancreatic tumours, all the seven ACCs were diffusely positive for the 2P-1-2-1 antibody. However, no positive staining was found in other pancreatic tumours including NETs, SPNs and ductal adenocarcinomas. The sensitivity and specificity of the 2P-1-2-1 antibody for ACCs were both 100%. In other organs studied, positive staining was observed only in the ectopic pancreas. ...

Accessory spleen or splenule is a common congenital anomaly in which an ectopic focus of normal splenic tissue is found separate from the main body of the spleen. They occur in approximately 10% of the population1,2. In the majority of cases these are located at or near the splenic hilum. The pancreatic tail is also a common location for these lesions occurring in approximately 16% or 61 of 364 in a large autopsy series by Halpert and Gyorkey1 and 21.8% on large CT series3. Splenules may range in size from a few millimeters to several centimeters however they are most typically less than 2cm1,3. They are usually single but may be multiple. The majority are asymptomatic incidental findings usually on CT or ultrasound of the abdomen. Rarely, they may become symptomatic because of rupture, hemorrhage, torsion or cyst formation3. The primary clinical significance of these lesions resides in their mimicry of neoplasm.. Differentiation between splenule or splenic lobulation and neoplasm may be ...

From our preliminary observation, it appears that GE cavitations are an aspect of more complex conditions associated with severe cerebral structural derangement. The awareness of this rare developmental abnormality involving the GE region may have implications in better understanding of the complex malformations caused by defective cellular proliferation and migration, such as lissencephalies. The fact that the lesions were bilateral and symmetric with an inverted regular open C shape, an epithelium-like lining, regular margins, and no apparent signs of hemorrhage (including the 2 cases with T1-weighted images) suggests a malformative rather than necrotic-clastic origin. Familial recurrence in 2 cases and the presence of frontal band heterotopias in 1 case further support such a hypothesis. Although the data are not extensive enough to conclude a statistical significance, the available ADC values (cases 1 and 4), albeit showing a slight trend toward mild reduction (0.85 SD, 0.09 m2/s), ...

Neuroglial cells constitute a separate class of cells in the nervous system; they have been studied intensively since their original description by Virchow in 1846. As a rule anatomists find no difficulty in recognizing them by their staining properties, their shape and configuration as well as by their characteristic location between and around neurons. Electron microscopy has in recent years added much important subcellular detail and has shown how intermingled neurons and glial cells are, being separated from each other by narrow clefts 100 to 200 Å wide (figures 1 A, B and 5, plates 1, 2 and 4). These studies have not changed the well-established grouping of mammalian glial cells into two main classes, the oligodendrocytes and the astrocytes. It is customary to state that glial cells outnumber neurons by 10 to 1 in the vertebrate nervous sytem. They are, however, smaller and according to some rough estimates they make up as much as 50% of the volume of mammalian brains. That glial cells ...

Prostate cancer fulfils some of the conditions required of a disease that might be managed by population screening. In a cohort of 50- to 60-year-old men, carrying out a rectal examination and prostate specific antigen (PSA) test will detect clinically suspicious areas within the prostate in approximately 5%, and approximately 10% will have a raised PSA. We are however unsure which of the prostate cancers that are known to be present in approximately 30-40% of men aged over 60 years will be detected. Eventually after such screening, around 4% of men with an otherwise normal prostate will be found to have prostate cancers. The use of rectal examination may increase the number of tumours found, but will reduce compliance. The use of free/total PSA ratios will reduce the number of unnecessary biopsies at the expense of missing some tumours. Of more concern, we remain uncertain how effective aggressive local treatment is in altering the natural history of the disease. The risk of a 50-year-old man with a 25
