Incidental discovery of a cerebellar developmental venous anomaly in a 48-year-old man investigated for right-sided sensorineural hearing loss. a T2-weighted image shows thin hypointense bands of flow void, in the right cerebellar hemisphere (open arrow). b SWI minIP demonstrates multiple thin medullary veins (arrows) that converge into a dilated collector vein (open arrow), consistent with a cerebellar venous angioma, better defined as developmental venous anomaly. c Post-contrast T1-weighted axial image shows the enhancing dilated veins (open arrow)
