Abstract
INTRODUCTION: A spinal dural arteriovenous fistula is a rare type of vascular malformation. If left untreated, these fistulas can result in significant neurological deficits secondary to spinal cord infarct or hemorrhage. CASE PRESENTATION: A 70-year-old female with a longstanding history of episodic progressive bilateral lower extremity weakness and sensory disturbances was previously misdiagnosed with multiple sclerosis. Imaging revealed a T2 signal change from T7 to the conus with associated signal change and she subsequently underwent a T10-L1 laminectomy for clip ligation of a spinal dural arteriovenous fistula. Here we present the clinical and radiographic progression of one patient with a spinal dural arteriovenous fistula. DISCUSSION: Spinal dural arteriovenous fistulas are a rare but treatable cause of myelopathy, so it is important to understand its natural progression and radiologic findings as it is frequently misdiagnosed.
