Developmental Venous Anomaly Presenting Intracranial Hemorrhage without Associated Vascular Anomaly

Abstract

Developmental venous anomalies (DVAs) are cited as the most common intracranial vascular anomaly. In the majority of cases, it has a benign clinical course, and complications such as intracranial hemorrhage (ICH) are rarely reported. In the rare cases of DVAs presenting ICH, the causes of hemorrhage are usually by a combined vascular anomaly, mostly cavernous malformation (CM) or complicated DVAs, such as thrombosis in the vein of DVAs. We report a rare case of uncomplicated DVA presenting hemorrhage without accompanied vascular anomaly, such as CM. The cause of hemorrhage is suggested to be a specific form of DVA, arterialized DVA. Arterialized DVAs should be noted that they have a greater risk of hemorrhage than classic DVAs.
