Presentation
Incidental findings for brain imaging after trauma.
Patient Data
A left temporal hyperdense linear structure is seen traversing both grey and white matter with no surrounding edema, likely a vessel… ? developmental venous anomaly.
A prominent venous structure is noted traversing the parenchyma of the left temporal lobe antro-posteriorly, with multiple variable sizes venous tributaries noted feeding into it, including a characteristic palm tree appearance of tributaries, noted just anterior to the left temporal horn of lateral ventricle. The anomalous vein is noted draining into a prominent left superficial middle cerebral vein and a prominent vein of Labbe into the left transverse sinus. No adjacent gliosis noted. No evidence of associated AV connection or nidus formation… Images are suggestive of a congenital developmental venous anomaly.
Case Discussion
Developmental venous anomaly (DVA), also known as cerebral venous angioma, is a congenital malformation of veins which drain the normal brain. They were thought to be rare before cross-sectional imaging but are now recognized as being the most common cerebral vascular malformation, accounting for ~55% of all such lesions.
