A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE. (from Stedman, 27th ed, 2000)
Veins draining the cerebrum.
A vascular anomaly that is a collection of tortuous BLOOD VESSELS and connective tissue. This tumor-like mass with the large vascular space is filled with blood and usually appears as a strawberry-like lesion in the subcutaneous areas of the face, extremities, or other regions of the body including the central nervous system.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
A vascular anomaly composed of a collection of large, thin walled tortuous VEINS that can occur in any part of the central nervous system but lack intervening nervous tissue. Familial occurrence is common and has been associated with a number of genes mapped to 7q, 7p and 3q. Clinical features include SEIZURES; HEADACHE; STROKE; and progressive neurological deficit.
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
The three membranes that cover the BRAIN and the SPINAL CORD. They are the dura mater, the arachnoid, and the pia mater.
Permanent dilation of preexisting blood vessels (CAPILLARIES; ARTERIOLES; VENULES) creating small focal red lesions, most commonly in the skin or mucous membranes. It is characterized by the prominence of skin blood vessels, such as vascular spiders.
Redness of the skin produced by congestion of the capillaries. This condition may result from a variety of causes.
Solitary or multiple benign hepatic vascular tumors, usually occurring in women of 20-50 years of age. The nodule, poorly encapsulated, consists of a central stellate fibrous scar and normal liver elements such as HEPATOCYTES, small BILE DUCTS, and KUPFFER CELLS among the intervening fibrous septa. The pale colored central scar represents large blood vessels with hyperplastic fibromuscular layer and narrowing lumen.
Elements of limited time intervals, contributing to particular results or situations.

Association of venous angioma and atypical meningioma--case report. (1/11)

A 67-year-old male presented with an atypical meningioma arising from the right tentorium associated with a venous angioma in the left cerebellar hemisphere. The venous angioma was detected incidentally during examinations for the brain tumor. The brain tumor was removed completely and the venous angioma followed conservatively. Venous angiomas associated with brain tumors should be followed conservatively, as the clinical significance and surgical indications are unclear.  (+info)

Midbrain venous angioma with obstructive hydrocephalus. (2/11)

A rare case of a mid brain venous angioma with obstructive hydrocephalus is described. A dilated draining vein from the lesion in the aqueduct as the cause of the hydrocephalus is highlighted, and interesting features of the pathology of venous angiomas and associated cavernous hemangioma are described. The management of this interesting condition is discussed.  (+info)

Histologically classified venous angiomas of the brain: a controversy. (3/11)

The term "venous angioma" (VA) usually refers to a developmental venous anomaly (DVA). However, a group of vascular malformations called VAs shows no venous abnormalities on angiography. The clinical and histological features of histologically classified VAs were studied in eight patients who presented with hemorrhage or seizures to reevaluate these venous anomalies. Angiography showed no venous abnormalities in six patients. Histological study included immunostaining for smooth muscle actin and glial fibrillary acidic protein. Surgical specimens of 10 cases of cavernous angiomas, 10 cases of arteriovenous malformations, and two cases of capillary telangiectasias were studied to compare these types of VAs. Angiographically occult VAs were surgically removed safely, whereas removal of DVAs was complicated by brain swelling and hemorrhagic infarction of the brain. Histological examination found angiographically occult VAs contained malformed and compactly arranged vessels with partly degenerated walls, whereas DVAs had dilated thin-walled vessels that were diffusely distributed in the normal white matter. This study of our cases and a review of the reported cases of VAs suggests that two different clinical and pathological entities are commonly categorized as "VA," angiographically occult VAs and DVAs. These two entities should be carefully distinguished.  (+info)

Atypical MR imaging perfusion in developmental venous anomalies. (4/11)

Developmental venous anomalies (DVAs) are common variants of cerebral venous drainage that are typically incidental findings on contrast-enhanced MR imaging studies. We present four cases of asymptomatic DVAs that demonstrate increased cerebral blood flow, cerebral blood volume, mean transit time, and time to peak on perfusion MR images. Our study indicates that alterations in perfusion MR imaging parameters can be seen with uncomplicated DVAs and do not necessarily imply a more ominous underlying etiologic factor, such as hypervascular tumor or stroke.  (+info)

Bilateral cerebral venous angioma associated with varices: a case report and review of the literature. (5/11)

A varix occurring with a cerebral venous angioma is a rare combination of cerebral vascular malformations. The most common vascular anomaly associated with a venous angioma is a cavernous angioma. We report a case of bilateral supratentorial venous angioma with 2 varices involving the angioma situated on the right frontotemporal region. Multiple subependymal veins were seen in the right supratentorial region, which joined to form multiple collector veins, which, in turn, unified into a tortuous channel in the region of the sylvian fissure and continued into venous varices.  (+info)

Treatment differences in cases with venous angioma. (6/11)

Venous angiomas were found to be the most common cerebral vascular malformations, composing 63% of such lesions in two autopsy series. Annual bleeding risk associated with venous angiomas is about 0.22 % per year. Venous angiomas are generally silent lesions because of their dynamic features, and are low flow and low pressure vascular structures draining normal brain tissue. An angioma rarely causes symptoms such as bleeding, seizure, hemifacial spasm, trigeminal neuralgia, aqueduct compression, nonhemorrhagic infarction and thrombosis of the draining vein. Even if it should bleed, the lesion can be managed conservatively in asymptomatic or mildly symptomatic patients. In this paper we report two venous angioma cases. The first patient bled twice in a short period of time and the angioma was located at the posterior fossa next to the left lateral recess. The second patient recently suffered a cerebral stroke that was located in the vicinity of the right caudate nucleus and not associated with the venous angioma that was located next to the left caudate nucleus. This patient had been under warfarin sodium treatment for 14 years due to his previous coronary artery bypass surgery, but unknowingly there was a venous angioma located next to the caudate nucleus.  (+info)

Cerebral venous angiomas are congenital anomalies of the intracranial venous drainage. Many believe that they are associated with a high risk of hemorrhage and neurological dysfunction, but newer neurodiagnostic imaging techniques are showing not only that they are more common than previously known …
Hemangioma, NOS (9120/0) and cavernous hemangioma (9121/0) arising in the dura and parenchyma of the brain/CNS are reportable.. Venous angiomas (9122/0) are not reportable wherever they arise. The primary site for venous hemangioma arising in the brain is blood vessel (C490). The combination of 9122/0 and C490 is not reportable. This is a venous abnormality. Previously called venous angiomas, these are currently referred to as a developmental venous anomalies (DVA).. ...

Gross et al reviewed hospital databases to identify children with CMs who had not been treated surgically and who had clinical and radiological follow-up. Annual hemorrhage rates were calculated in lesion-years, and risk factors were assessed using the Cox regression. In a cohort of 167 patients with 222 CMs, the mean patient age at the time of diagnosis was 10.1 years old (SD 6.0). Ninety patients (54%) were male. One hundred four patients (62%) presented with hemorrhage from at least 1 CM, 58 (35%) with seizures with or without CM hemorrhage, and 43 (26%) with incidental lesions. Twenty-five patients (15%) had multiple CMs, 17 (10%) had a family history of CMs, and 33 (20%) had radiologically apparent developmental venous anomaly (DVAs). The overall annual hemorrhage rate was 3.3%. Permanent neurological morbidity was 29% per hemorrhage, increasing to 45% for brainstem, thalamic, or basal ganglia CM and decreasing to 15% for supratentorial lobe or cerebellar lesions. The annual hemorrhage rate ...
We have undertaken this qualitative analysis to evaluate a relatively large number of cases with both structural imaging (principally MR imaging) and metabolic functional imaging with FDG-PET. In this study, cortical hypometabolism associated with a DVA was observed in more than two-thirds of the 25 cases identified, supporting our hypothesis that the metabolic activity in the brain parenchyma in the region of a DVA is not necessarily definitively normal. This finding challenges the conventional understanding that DVAs are clinically inconsequential and do not affect adjacent brain parenchyma,3 though the significance of any metabolic abnormality remains uncertain.. The etiology of hypometabolism in the brain parenchyma drained by a DVA is unclear and may reflect an intrinsic, possibly developmental, neuronal abnormality or an acquired abnormality secondary to derangement of blood flow. We observed an association between the degree of DVA-associated hypometabolism and increased age of the ...
All complex functions of the human body require the communication between cells and cell networks. Our aim is to understand how cells generate electrical and chemical signals and how such signals are transmitted from one cell to the other, with particular interest into electrical signaling of neurons and synaptic transmission in the brain. We study cell signaling with biophysical methods, explore the function of ion channels and transporters with computational and experimental approaches, and analyze the impact of these transport processes for the cell function. By examining pathomechanisms underlying human diseases we seek to understand how altered cell signaling causes cell and organ dysfunction ...

G amma knife radiosurgery (GKRS) has been used for the treatment of arteriovenous malformations (AVMs) since 1970; 21 the favorable results 20 of this procedure prompted pilot series in which GKRS was used to treat venous angiomas 15 and cavernous malformations (CMs). 24 We first used GKRS to treat a patient with a CM in 1985. In the first half of the present series, we used radiation doses comparable to those used in the treatment of AVMs. This resulted in a high incidence of complications, and we changed the protocol to lower radiation doses for the. ...
I have been in the hosptial for 5 days. What brought me there was a sudden intense burning sensation in the right side of my head, sudden vomiting, I lost my balance I couldnt walk straight or see straight. I was having violent jerks which ended up going into a full blown seizure. It hurts into my neck and jaws. They done a 24 hour EEG, 2 MRIs one of my head one of my neck and an MRA. This has all been happening for about 4 weeks. The only thing I was told was found on my MRI was that I have a venous angioma that I didnt need to worry about as long as I stay clear of blood thinners and head trauma. then they said I needed to see a dentist about my jaws hurting. They also said they had no idea why my head was burning. And theyve sent me to pain management today where I had 12 shots in the base of my head neck upper back and shoulder blades. And i have to go again for these shots in 3 weeks. Yet the burning sensation in my head has not stopped or eased up. In the hospital they were giving me ...

DUBLIN, May 23, 2019 /PRNewswire/ -- The Pain Therapeutics - Drugs, Markets and Companies report from Jain PharmaBiotech has been added to ResearchAndMarkets.coms offering. This report describes the latest concepts of pathomechanisms of pain as a basis for management and development of new pharmacotherapies for pain. Major segments of the pain market are arthritis, neuropathic pain and cancer pain. Because pain is a subjective sensation, it is difficult to evaluate objectively in clinical trials. Various tools for pain measurement are described, including brain imaging.. Most of the currently used analgesic drugs fall into the categories of opioids and nonsteroidal anti-inflammatory drugs such as COX-2 inhibitors. Non-opioid analgesics include ketamine, a N-methyl-D-aspartate receptor antagonist. Adjuvant analgesics include antidepressants and antiepileptic drugs used for the treatment of neuropathic pain. Management of pain is multidisciplinary and includes both pharmacological and ...

Red moles, or cherry angiomas, are common skin irregularities that can develop on most areas of the body, most commonly on the torso, arms, legs, and shoulders. Also known as senile angiomas or Campbell de Morgan spots, cherry angiomas are often bright red, circular or oval in shape, and small - usually ranging in size from a pinpoint to about one-fourth of an inch in diameter. Some cherry angiomas appear smooth and even with your skin, while others appear slightly raised. The collection of small blood vessels inside a cherry angioma give them a reddish appearance. This type of skin irregularity is typically not a cause for concern unless it bleeds often or changes in size, shape, or color ...
BACKGROUND: Angioma serpiginosum (AS) is a rare vascular abnormality consisting of proliferation and dilation of superficial blood vessels in the skin. AS typically presents in the first 2 decades of life and remains stable with time. CASE SUMMARY: We report the case of a 13-year-old female with an acquired, recurrent erythematous lesion with serpiginous borders on her left upper arm. Over several years, the lesion reappeared then disappeared 12 to 15 times. At one point, she developed a tender red nodule within the lesion; consequently, a biopsy was taken, revealing dilated telangiectatic vessels in the dermal papillae with mild, focal extravasation of erythrocytes ...
