Developmental venous anomaly

Discussion:

Findings on the CT angiogram are fairly characteristic of a developmental venous anomaly. These are most often an incidental finding and are only uncommonly symptomatic. DVAs have a close associated with cavernomas, while one is not distinctly identified on the MRI there is triangular-shaped susceptibility artifact adjacent to the DVA, which is probably due to old hemorrhage possibly from an underlying cavernoma. In this case the DVA is thought to be incidental to presentation.
