Core Tip	Spinal cord perimedullary arteriovenous fistulas (PMAVF) in adults are rare and frequently misdiagnosed. We report a case of PMAVF with a prior history of lumbar disc disease, which was operated on, now presenting with slowly progressive sensorimotor lower limb weakness and bladder disturbance, misdiagnosed as lumbar disc disease, and operated on without complete resolution. Steroids administered based on magnetic resonance cord hyperintensities resulted in transient and remarkable worsening of paraparesis. Following digital subtraction angiography, a diagnosis of PMAVF was made, and the fistula was cauterized. Steroid-aggravated weakness is a diagnostic clue for PMAVF.
