The authors report the unique case of a patient with a thoracic spinal dural arteriovenous fistula (DAVF) causing remote brainstem symptoms of positional vomiting and minimal vertigo. Magnetic resonance (MR) imaging of the brain demonstrated high signal abnormality in the medulla, presumably related to venous hypertension, and spinal MR imaging revealed markedly dilated veins along the dorsal aspect of the cord. Spinal angiography confirmed the presence of a thoracic spinal DAVF. Disconnection of the DAVF from the spine resulted in a marked improvement in symptoms and resolution of the preoperative MR imaging-documented abnormalities. The authors highlight the rare syndrome of positional vomiting as a brainstem symptom and conclude that spinal DAVFs should be considered in the differential diagnosis of high signal MR imaging abnormalities localized to the brainstem. |
