Objective and Importance: Developmental venous anomalies (DVAs) are common congenital anomalies of intracranial venous drainage. In general, it is felt that DVAs replace the normal venous drainage system and, unless associated with another lesion such as a cavernous malformation, should not produce symptoms. The present case raises important questions regarding the potential for DVAs to become symptomatic and the role of venous hypertension in this process.
