We report the case of an 8-year-old boy with a huge intradural spinal arteriovenous fistula (AVF), which was successfully obliterated by surgery. The symptoms were episodic headaches and progressive motor and sensory deficits. He had suffered a subarachnoid hemorrhage twice before but no ensuing neurological deficits. Neuroradiological examinations revealed an intradural AVF with a huge venous aneurysm ventral to the spinal cord of C7 to T2, which was fed by the left 5th intercostal artery and the right thyrocervical artery. These two feeding arteries were occluded intradurally just at the venous aneurysm emerging point. MR images taken sequentially after surgery demonstrated complete thrombosis and subsequent disappearance of the thrombosed malformation. Neurological symptoms improved gradually. Treatment of such malformations is discussed.
