Cavernous Angioma Coexisting with Venous Angioma in the Posterior Fossa

ABSTRACT

Venous angioma and cavernous angioma have its own distinctive characteristics in the pathological, radiological, and clinical points of view. However, the chances of coexistence of two disease entities as the neuroimaging techniques developed, and highlight the possibility made us suspect that they might share the same pathogenesis. When they coexist, the clinical symptoms are almost always caused by cavernous angioma. Here, we report 2 cases of cavernous angioma coexisting with a venous angioma in the posterior fossa presenting acute brainstem dysfunction.
