A 24-year-old man presented with a left facial partial seizure. He had no neurological deficit. Brain magnetic resonance imaging showed a possible vascular malformation in the deep right frontal semiovale white matter, a serpiginous structure extending toward the medial right convexity, demonstrating a flow void on T2 images. There was no parenchymal or extraaxial hemorrhage.
Digital subtraction angiography revealed a large developmental venous anomaly (DVA) in the paramedian right midfrontal lobe, draining the deep white matter via 2 transcortical veins toward the anterior superior sagittal sinus, that resembled a caput medusae.
