Spinal dural AVF is the most common type of spinal AVMs. It affects especially old male with slowly progressive paraparesis in most cases. We have experienced a rare case of a middle aged male with spinal dural AVF who showed rapid deterioration in its course. The patient was treated with surgical interruption of AVF after transarterial embolization with NBCA. The patient improved well after the treatment,and intramedullary lesion on MRI disappeared after 4 years. The authors would like to stress the importance of early diagnosis and proper treatment for spinal dural AVFs.
