Abstract

Developmental venous anomalies (DVAs) are the most commonly encountered cerebral malformations. While generally asymptomatic and discovered as incidental findings, there is a small number that can cause intracranial haemorrhage, usually attributed to associated cavernomas; however, venous thrombosis of the draining vein is a rare cause. A 10-year-old woman presented with seizure episodes. Angiographic evaluation revealed a collection of vessels draining into the superior sagittal sinus via the vein of Trolard, concerning for a DVA. The patient improved clinically with supportive care and antiepileptic treatment. Anatomically, DVAs represent dysplasia of primary capillary beds and smaller cerebral veins, resulting in abnormal venous drainage of the affected parenchyma. Several distinguishing radiological findings can help differentiate a DVA from other pathologies. Early radiological identification can help in the initiation of appropriate therapy and prevent incorrect surgical management leading to further neurological demise.
