Abstract
BACKGROUND AND PURPOSE: We present a case of magnetic resonance imaging (MRI)-occult intracranial dural arteriovenous fistula (DAVF) with serious cervical myelopathy and review the pathophysiological background. SUMMARY OF CASE: A 61-year-old man had suffered from progressive neurological deterioration. He had demonstrated swollen spinal cord with diffuse enhancement and no dilated vascularity on MRI. Finally, digital subtraction angiography revealed DAVF at the petrous ridge and it was successfully treated by embolization. CONCLUSION: A slow flow DAVF is not readily recognizable on MRI. Whenever a patient presents with unexplainable progressive myelopathy, a possibility of vascular origin has to be considered.
