Cerebellar cavernous angioma associated with developmental venous anomaly presenting as a cerebellopontine angle neoplasm in CT scan.

Abstract

Association of developmental venous anomaly (DVA) and cavernous malformation (CM) of the posterior fossa is rare. If bleeding occurs, it must be assigned to the CM. Developmental venous anomalies, considered as normal vascular variation, are rarely symptomatic. Indeed, the CMs are true malformations and have a high bleeding potential.
