Hemorrhagic presentation without venous infarction caused by spontaneous thrombosis of developmental venous anomaly and angiographic change after treatment

Developmental venous anomalies (DVAs) have been known benign anatomical variations and generally do not cause symptoms. Although several cases of venous infarction caused by DVA thrombosis have been reported, it not common in itself. But only hemorrhagic presentation in DVA is extremely rare. We describe a case with large intracerebral hemorrhage (ICH) without venous infarction caused by DVA thrombosis and angiographic change of successful treatment.
