BACKGROUND: Spinal dural arteriovenous fistulas (DAVFs) are usually associated with neurologic dysfunction adjacent to the shunt point; however, the symptoms are uncommon far from the site of the fistula. To our knowledge, this is the first report of a patient with rapidly progressive isolated pseudobulbar palsy because of thoracic DAVF.
CASE DESCRIPTION: We report a patient with thoracic DAVF presenting with remote symptoms of brainstem congestion. The patient was a 36-year-old man who presented with a sudden history of vomiting, dysphagia, and flaccid weakness in the 4 limbs. Intracranial magnetic resonance (MR) imaging at a local hospital demonstrated T2 signal hyperintensity within the medulla, and he was referred to our hospital for a suspected brainstem lesion. However, cervical MR imaging revealed a dilated and tortuous perimedullary venous plexus, and spinal angiography revealed DAVF in T5-6 with a feeding artery from the intercostal artery. After obliteration of the fistula, the progression of the disease was stopped and the symptoms improved.
CONCLUSIONS: Although rare, thoracic DAVFs may present symptoms resembling brainstem infarction. Prompt surgical intervention is necessary for patients with thoracic DAVF presenting with rapidly progressive pseudobulbar palsy.
