A Rare Case of Supratentorial Cavernous Angioma Associated with Arterialized Developmental Venous Anomaly

Matteo Martinoni et al. Asian J Neurosurg. 2019 Jul-Sep.

Abstract

The association of cavernous malformations and developmental venous anomalies (DVA) is well known, but the presence of arterial fistulous connection with the main venous collector has been reported in the literature only once. We report the unusual case of a hemorrhagic cavernous angioma associated with DVA characterized by a fine arterial supply to the main venous collector. During surgery, after the excision of the cavernous angioma, few small arterial feeders were found entering the main channel of the venous developmental anomaly. The presence of an arterial fistulous connection with the main venous collector of a DVA may be a possible mechanism involved in a higher bleeding potential of cavernous angioma.

Keywords: Cavernous malformation; cerebral hemorrhage; developmental venous anomalies; developmental venous anomaly; venous angioma.
