Thrombosed developmental venous anomaly associated with cerebral venous infarct.

E-mail: [email protected] Developmental venous anomaly (DVA), also known as venous angioma, is becoming the most commonly encountered intracranial vascular malformation in central nervous system (CNS) imaging. It is thought that DVA develops during development of the venous system which results in the preservation of primitive embryological medullary veins, draining into a single longer vein. Thrombosis of the collector vein of a DVA is a rare complication leading to cerebral venous infarction (CVI).
