Cerebellar venous angioma: "benign" entity?

W E Rothfus, A L Albright, K F Casey

    AJNR. American Journal of Neuroradiology
    |January 1, 1984
    PubMed
    Summary

    Bleeding venous angiomas in the cerebellum can cause serious, recurrent hemorrhages. These cerebellar venous malformations may bleed more often than those in other brain areas.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Vascular Malformations

    Background:

    • Venous angiomas are vascular malformations that can occur in the brain.
    • Cerebellar hemorrhages can arise spontaneously from various causes.

    Observation:

    • This report details four patients with bleeding venous angiomas specifically in the cerebellar hemispheres.
    • All reported hemorrhages were subacute, with three patients experiencing recurrent bleeding events.

    Findings:

    • Venous angiomas are a recognized cause of spontaneous cerebellar hemorrhage.
    • Cerebellar venous angiomas appear to have a higher propensity for bleeding compared to venous angiomas in other locations.
    • The natural history of cerebellar venous angiomas resembles that of arteriovenous malformations.

    Implications:

    • While not all venous angiomas bleed, those in the cerebellum may present with acute, subacute, recurrent, or even catastrophic hemorrhages.
    • The clinical course of cerebellar venous angiomas is not always benign, necessitating careful consideration.
    • These findings highlight the importance of recognizing cerebellar venous angiomas as a potential source of serious intracranial bleeding.
