A 53-year-old man abruptly developed headache and unconsciousness. Brain computed tomography (CT) and CT angiography showed subarachnoid hemorrhage, intraventricular hemorrhage, and multiple tortuous vascular structures on the brain stem and upper cervical spinal cord. Four-vessel angiography displayed intradural ventral arteriovenous fistula, supplied by the left vertebral and occipital arteries. Drainage was via both sigmoid sinus and cervical venous plexus. He had been treated with transarterial coil embolization of the left vertebral artery. Subsequently, he suffered from left hemiplegia and cognitive problem. Brain magnetic resonance (MR) and MR angiography performed 4 weeks later revealed multiple infarctions on the left cerebellum, left upper cervical spinal cord, and both medial thalamus, as well as occlusion of the left vertebral artery with reduction in varix size. After rehabilitative management, his muscle strength and cognitive function improved. We report a very rare case of dural arteriovenous fistula on the brain stem and upper cervical spinal cord.

A 49-year-old man received prolotherapy in the upper cervical region at a local medical clinic. Immediately after the procedure, he felt a sensation resembling an electric shock in his right upper and lower extremities, and continuously complained of numbness and discomfort in the right hemibody. He visited our clinic a week later. Upon physical examination, there were no significant abnormal findings. The visual analog scale was 60 points. T2-weight magnetic resonance images of the cervical spine showed a 0.7 cm sized bright oval spot on the right side of the spinal cord at the level of C4-C5 disc, suggesting spinal cord injury. There were no definite electrodiagnostic abnormalities. Digital infrared thermal images showed moderately decreased surface temperature on lateral aspect of the right forearm and dorsum of the right hand compared with the other side. Considering that very rare complications like spinal cord injury may develop after prolotherapy, we suggest that special interventions such as prolotherapy be performed by professional experts.
