Case Reports
Developmental venous anomaly presenting as a spontaneous intraparenchymal hematoma without thrombosis.
Developmental venous anomalies (DVAs) are cited as the most common cerebral vascular malformations. Still, intracerebral hematomas are rarely thought to be caused by DVAs. In this report, the authors present a unique case of a DVA that hemorrhaged spontaneously, rather than hemorrhaging into a venous infarction following DVA thrombosis as has been more commonly reported. ⋯ Few reports have cited DVA as the sole cause of intracerebral hemorrhage. While very rare, these reports suggest hemorrhagic conversion of a venous infarction secondary to a thrombosed DVA as a possible etiology, and several provide imaging consistent with this diagnosis. This case study demonstrates a unique presentation of a hemorrhagic DVA in the absence of thrombosis or stroke.
