Developmental Venous Anomaly

developmental venous anomaly
Also known as a venous angioma, a developmental venous anomaly (DVA) is a venous malformation in the brain. The DVA in this patient exhibits the classic caput medusae of veins draining into a larger vein which, in this case, then drains into the cavernous sinus. For futher information on DVAs see previous case in the cerebellum and previous case in the pons.
