Developmental Venous Anomaly Angiography

A 34-year-old man with headache and diplopia had a mass on magnetic resonance imaging with a prominent transmedullary vein consistent with developmental venous anomaly (DVA). Catheter angiography showed mid-to-late arterial phase opacification of the DVA (arrow) draining to the transmedullary vein. The patient underwent resection of the mass, which was confirmed to be glioblastoma multiforme. Postoperative imaging showed complete resection of the DVA in the process. Developmental venous anomalies are abnormal connections between cerebral superficial and deep venous systems and are the most common type of cerebral vascular malformation. This case may be the first reported instance of a DVA within an intracranial neoplasm. Click the related article link for full clinical details.
