Spinal Dural Arteriovenous Fistula Assumed to be Symptomatic after Placement of Lumbar Cerebrospinal Fluid Drain

A 69-year-old man presented with severe headache. Cranial computed tomography revealed diffuse subarachnoid hemorrhage. An anterior communicating artery aneurysm was identified and successfully obliterated by open microsurgery on the same day. Following placement of a continuous lumbar cerebrospinal fluid drain on hospitalization day 7, the patient developed a severe paraplegia and sensory loss below T6. Cerebral magnetic resonance imaging did not identify a responsible lesion. Spinal magnetic resonance imaging, however, showed extensive intramedullary hyperintensity on T2-weighted sequences.
