Small isolated paraspinal arteriovenous fistula

Department of Radiology, Chang Gung Memorial Hospital and Medical College, Taipei, Taiwan.

We report a case of a small, isolated paraspinal arteriovenous fistula (AVF) that arose in an adult without obvious trauma. The fistula, despite its extraspinal location and small size, caused hypertension of the intrathecal venous system and produced symptoms that were similar to those of spinal dural AVF. Detecting such a small lesion is difficult, but contrast-enhanced MR imaging can prove helpful in this regard.
