  2. Developmental venous anomaly - Wikipedia

    en.wikipedia.org/wiki/Developmental_venous_anomaly

    A developmental venous anomaly (DVA, formerly known as venous angioma) is a congenital variant of the cerebral venous drainage. On imaging it is seen as a number of small deep parenchymal veins converging toward a larger collecting vein.

  3. Cranial venous outflow obstruction - Wikipedia

    en.wikipedia.org/wiki/Cranial_venous_outflow...

    The pathophysiology of cranial venous outflow obstruction involves the disruption of normal venous drainage from the brain. Cerebral veins play a crucial role in draining brain interstitial fluid (ISF), and their significance has been linked in various neurological conditions. [1] It can be caused by extrinsic or intrinsic anomalies. [7]

  4. Cavernous hemangioma - Wikipedia

    en.wikipedia.org/wiki/Cavernous_hemangioma

    The treatment approach depends on the site, size and symptoms present, as well as the history of hemorrhage from the lesion. [27] Microsurgery is generally preferred if the cerebral cavernous hemangioma is superficial in the central nervous system, or the risk of damage to surrounding tissue from irradiation is too high.

  5. Central nervous system cavernous hemangioma - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system...

    Developmental venous abnormality seen on a (T1 axial contrast enhanced) MRI. In up to 30% there is a coincidence of CCM with a venous angioma, also known as a developmental venous anomaly . These lesions appear either as enhancing linear blood vessels or caput medusae , a radial orientation of small vessels that resemble the hair of Medusa from ...

  6. Vascular anomaly - Wikipedia

    en.wikipedia.org/wiki/Vascular_anomaly

    Venous malformation is a bluish lesion compressible on palpation; the masses enlarge with physical activity or if in a dependent position. The bluish lesion is caused by dilated venous vessels. Venous malformations can be painful in the morning due to stasis and microthrombi within the veins. Venous malformations usually occur in the head and ...

  7. Vascular malformation - Wikipedia

    en.wikipedia.org/wiki/Vascular_malformation

    A vascular malformation is a type of vascular anomaly. [2] They may cause aesthetic problems as they have a growth cycle, and can continue to grow throughout life. Vascular malformations of the brain include those involving capillaries, and those involving the veins and arteries.

  8. Cerebral arteriovenous malformation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteriovenous...

    Other common symptoms are a pulsing noise in the head, progressive weakness, numbness and vision changes as well as debilitating, excruciating pain. [4] [5] In serious cases, blood vessels rupture and cause bleeding within the brain (intracranial hemorrhage). [a] In more than half of patients with AVM, this is the first symptom. [7]

  9. Vein of Galen aneurysmal malformations - Wikipedia

    en.wikipedia.org/wiki/Vein_of_Galen_aneurysmal...

    These treatments are preferred because they offer little threat to the surrounding brain tissue. However, there have been several reported cases of arteriovenous malformations recurring. [ 12 ] The young age of many patients, the complex vascular anatomy, and the sensitive location of the Vein of Galen offer considerable challenges to surgeons ...
