Transfontanelle ultrasonography of infant brain: analysis of findings in 114 patients in Benin City, Nigeria. (4/12)

OBJECTIVES: To analyse the pattern of findings in sonographic examination of infant brains. SETTING: Radiology Department of a University Teaching Hospital. MATERIALS AND METHODS: The ultrasound request cards, reports and case notes of 114 consecutive term infants who underwent transfontanelle ultrasonography over a four-year period (between 1st May 2000 and 31st April 2004) were retrospectively analysed. The transfontanelle ultrasonographies were done using a two dimensional Sonoace 1500 (Medison Inc, South Korea 1995) ultrasound scanner fitted with 6.5 megahertz (MHz) curvilinear small head probe. The scans were done in both coronal and sagittal sections applying the standard techniques. RESULT: Atotal of 114 infants were seen in the study period with male to female ratio of 1:1. Sixty eight patients (59.65%) presented within the first 2 months of age. Hydrocephalus 34 (29.04%), seizure disorders 16 (14.04%) and suspected intracranial bleeding 19 (16.67%) constituted over half of the presenting complaints. The result showed that 54 patients (47.37%) had normal findings, 43 (37.72%) had hydrocephalus of which in 25 (21.93%) it was communicating while in 18 (15.79%) it was non-communicating 6 (5.26%) had cephalohaematoma, 5 (4.39%) had encephalcoele, 4 (3.51%) had periventricular leukomalacia, and 2 (1.75%) had subgaleal cyst. CONCLUSION: Transfontanelle ultrasonography is a useful technique for diagnosis of lesions within the infant brain. Hydrocephalus is the most frequent reason for request of transfontanelle ultrasound scan and also the most frequent abnormal finding.  (+info)

Brain herniation in a neonate. (5/12)

Brain herniation is generally thought to be unlikely to occur in newborns due to the presence of the patent fontanelles and cranial sutures. A review of the literature published from 1993 to 2008 via MEDLINE search revealed no reports on neonatal brain herniation from intracranial tumour. We report a preterm Malay male infant born via elective Caesarean section for antenatally diagnosed intracerebral tumour, which subsequently developed herniation. Cerebral magnetic resonance imaging showed features that were compatible with a large complex intracranial tumour causing mass effect and gross hydrocephalus. Tumour excision was scheduled when the infant was two weeks old. Unfortunately, on the morning of the surgery, he developed signs of brain herniation and had profuse tumour haemorrhage during the attempted excision. Histopathological examination revealed an embryonal tumour, possibly an atypical rhabdoid/teratoid tumour. This case illustrates that intracranial tumours in newborns can herniate and should therefore be closely monitored.  (+info)

Anterior fontanelle size in healthy Iranian neonates on the first day of life. (7/12)

There is limited data in the literature on the normal size of the anterior fontanelle. This cross- sectional study was to determine normal values of anterior fontanelle size on the first day of life, using standard methods. Anterior fontanelle size was measured in 400 term and healthy neonates delivered at the Shariati Hospital, Tehran, Iran. Examination included assessment of head circumference, anterior fontanelle size, weight, length. Type of delivery was also recorded. The mean size of anterior fontanelle was 25.34 +/- 13.27 mm, and it was established in both genders, 26.70 +/- 13.19 mm in boys, and 23.67 +/- 13.20mm in girls. A significant difference between the mean anterior fontanelle size in boys and girls was found (P=0.023). There was no significant difference in anterior fontanelle size between the infants born with a normal vaginal delivery and those with cesarean-section (P=0.08). There was found a significant negative correlation between the mean size of anterior fontanelle size with both weight and height (P<0.05). No significant correlation was found between mean size of anterior fontanelle and head circumference or with gestational age of infant (P>/=0.05). Our results proved possible to define a references range and centile chart. The method used is simple and accurate and easy used in the routine neonatal examination.  (+info)

Preterm screening by transfontanelar ultrasound - results of a 5 years cohort study. (8/12)

OBJECTIVES: Intracranial hemorrhages (ICH) might be the cause of significant psycho-motor or cognitive impairment in preterm babies. A 5 year cohort study performed in the IOMC was aimed at determining the prevalence and proportion of the main types of ICH diagnosed by transfontanelar (TF) ultrasound among admitted preterms, along with the neuro-developmental effects on a 12 month follow-up period. MATERIAL AND METHODS: In the above mentioned period all enrolled newborns were examined by TF ultrasound according to a common standardized protocol. The 4 grade Papile ICH classification was used for all examined subjects. In order to determine the potential neurological sequels we performed a 12 month neurological follow-up of all 292 patients in the study group. RESULTS: The prevalence of all types ICH diagnosed by systematic TF ultrasound was 20.4 %. The most prevalent type of ICH was peri-intraventricular: 40% grade I and 33 % grade II, with no major neurological sequels For both the correlation to the neurological outcome was statistically significant (p < 0.05). Severe neurological sequels were associated with grade III and IV, but the correlation was found to be statistically significant (p < 0.05) only for grade IV hemorrhages. A severe neurological outcome was of statistical significance only for the cerebellar hemorrhage outcome, although a similar pattern was also observed for the thalamic hemorrhages. CONCLUSION: Systematic TF screenings for preterm is useful for early diagnosis and staging which might improve the management of rehabilitation therapies, and provide appropriate information on the disease outcome as well as influencing the quality of parental counseling.  (+info)

Cranial fontanelles, also known as "soft spots," are the membrane-covered spaces between the bones of a newborn or infant's skull. There are six fontanelles in total: two anterior (frontal) fontanelles, two posterior (occipital) fontanelles, and two smaller sphenoid and mastoid fontanelles.

The anterior fontanelle is the most prominent and is located towards the front of the head. It typically measures about 1 to 2 inches in diameter at birth and closes by around 18-24 months of age as the bones of the skull grow together. The posterior fontanelle is smaller, located towards the back of the head, and usually closes by around 2 months of age.

The fontanelles allow for the baby's brain to grow rapidly during the first few months of life, and they also provide some flexibility during childbirth, allowing the skull bones to overlap and make it easier for the baby to pass through the birth canal. It is important to handle a newborn gently, especially around the fontanelles, as they are still developing and can be injured easily.

Cranial sutures are the fibrous joints that connect and hold together the bones of the skull (cranium) in humans and other animals. These sutures provide flexibility for the skull during childbirth and growth, allowing the skull to expand as the brain grows in size, especially during infancy and early childhood.

There are several cranial sutures in the human skull, including:

1. The sagittal suture, which runs along the midline of the skull, connecting the two parietal bones.
2. The coronal suture, which connects the frontal bone to the two parietal bones.
3. The lambdoid suture, which connects the occipital bone to the two parietal bones.
4. The squamosal suture, which connects the temporal bone to the parietal bone.
5. The frontosphenoidal and sphenoethmoidal sutures, which connect the frontal bone, sphenoid bone, and ethmoid bone in the anterior cranial fossa.

These sutures are typically made up of a specialized type of connective tissue called Sharpey's fibers, which interdigitate with each other to form a strong yet flexible joint. Over time, as the skull bones fully fuse together, these sutures become less prominent and eventually ossify (turn into bone). In some cases, abnormalities in cranial suture development or fusion can lead to medical conditions such as craniosynostosis.

The anterior cranial fossa is a term used in anatomy to refer to the portion of the skull that forms the upper part of the orbits (eye sockets) and the roof of the nasal cavity. It is located at the front of the skull, and is formed by several bones including the frontal bone, sphenoid bone, and ethmoid bone.

The anterior cranial fossa contains several important structures, including the olfactory bulbs (which are responsible for our sense of smell), as well as the optic nerves and parts of the pituitary gland. This region of the skull also provides protection for the brain, particularly the frontal lobes, which are involved in higher cognitive functions such as decision-making, problem-solving, and emotional regulation.

Abnormalities or injuries to the anterior cranial fossa can have serious consequences, including damage to the olfactory bulbs, optic nerves, and pituitary gland, as well as potential injury to the frontal lobes of the brain.

The posterior cranial fossa is a term used in anatomy to refer to the portion of the skull that forms the lower, back part of the cranial cavity. It is located between the occipital bone and the temporal bones, and it contains several important structures including the cerebellum, pons, medulla oblongata, and the lower cranial nerves (IX-XII). The posterior fossa also contains the foramen magnum, which is a large opening through which the spinal cord connects to the brainstem. This region of the skull is protected by the occipital bone, which forms the base of the skull and provides attachment for several neck muscles.

A dermoid cyst is a type of benign (non-cancerous) growth that typically develops during embryonic development. It is a congenital condition, which means it is present at birth, although it may not become apparent until later in life. Dermoid cysts are most commonly found in the skin or the ovaries of women, but they can also occur in other areas of the body, such as the spine or the brain.

Dermoid cysts form when cells that are destined to develop into skin and its associated structures, such as hair follicles and sweat glands, become trapped during fetal development. These cells continue to grow and multiply, forming a sac-like structure that contains various types of tissue, including skin, fat, hair, and sometimes even teeth or bone.

Dermoid cysts are usually slow-growing and may not cause any symptoms unless they become infected or rupture. In some cases, they may cause pain or discomfort if they press on nearby structures. Treatment typically involves surgical removal of the cyst to prevent complications and alleviate symptoms.

Cleidocranial dysplasia is a genetic skeletal disorder that affects the development of bones and teeth. The condition is characterized by the underdevelopment or absence of the collarbones (clavicles), which can result in shoulder joints that are abnormally close together. This may allow the person to bring their shoulders around to touch or even overlap in front of their body.

People with cleidocranial dysplasia also often have a delayed closure of the fontanels (soft spots) on the skull, as well as an abnormal shape and size of the head. The facial bones may be underdeveloped, leading to a sunken appearance in the middle of the face and a prominent forehead. Dental abnormalities are also common, such as missing or delayed eruption of teeth, extra teeth, and misaligned teeth.

Cleidocranial dysplasia is caused by mutations in the CBFA1/RUNX2 gene and is inherited in an autosomal dominant manner, meaning that a child has a 50% chance of inheriting the condition if one of their parents is affected. However, many cases result from new mutations in the gene and occur in people with no family history of the disorder. Treatment typically involves surgical procedures to correct skeletal abnormalities and dental issues, as well as orthodontic treatment to align teeth.

The skull is the bony structure that encloses and protects the brain, the eyes, and the ears. It is composed of two main parts: the cranium, which contains the brain, and the facial bones. The cranium is made up of several fused flat bones, while the facial bones include the upper jaw (maxilla), lower jaw (mandible), cheekbones, nose bones, and eye sockets (orbits).

The skull also provides attachment points for various muscles that control chewing, moving the head, and facial expressions. Additionally, it contains openings for blood vessels, nerves, and the spinal cord to pass through. The skull's primary function is to protect the delicate and vital structures within it from injury and trauma.

A forehead, in medical terms, refers to the portion of the human skull that lies immediately above the eyes and serves as an attachment site for the frontal bone. It is a common area for the examination of various clinical signs, such as assessing the level of consciousness (by checking if the patient's eyebrows or eyelids twitch in response to a light touch) or looking for signs of increased intracranial pressure (such as bulging fontanelles in infants). Additionally, the forehead is often used as a site for non-invasive procedures like Botox injections.

A subdural effusion is an abnormal accumulation of fluid in the potential space between the dura mater (the outermost layer of the meninges that covers the brain and spinal cord) and the arachnoid membrane (one of the three layers of the meninges that surround the brain and spinal cord) in the subdural space.

Subdural effusions can occur due to various reasons, including head trauma, infection, or complications from neurosurgical procedures. The fluid accumulation may result from bleeding (subdural hematoma), inflammation, or increased cerebrospinal fluid pressure. Depending on the underlying cause and the amount of fluid accumulated, subdural effusions can cause various symptoms, such as headaches, altered mental status, or neurological deficits.

Subdural effusions are often asymptomatic and may resolve independently; however, in some cases, medical intervention might be necessary to alleviate the pressure on the brain or address the underlying condition. Imaging techniques like computed tomography (CT) or magnetic resonance imaging (MRI) scans are typically used to diagnose and monitor subdural effusions.
