The FLAIR images are apparently normal.
The post-contrast images show enhancing cortical venous tributaries in the left parietal cortex converging into a large draining vein (yellow arrows) that further drains into a subependymal vein.
There is no evidence of ischemia or edema seen.
Case Discussion
Developmental venous anomalies(DVA) aka venous angioma represent variations of normal venous drainage rather than true malformations.
Patients are usually asymptomatic
It consists of tortuous tributary veins that converge on an enlarged draining vein giving a "caput medusae" appearance.
