Oculomotor palsy and papilledema with pial-dural arteriovenous malformation

A 62-year-old man presented with papilledema, a cranial bruit, and a partial left oculomotor nerve palsy. Arteriography revealed a large mixed pial-dural arteriovenous malformation involving the superior sagittal and both transverse sinuses. After the superior part of the malformation was embolized, the patient's papilledema and ocular motility disturbance resolved. The oculomotor disturbance may have been a nonspecific sign of increased intracranial pressure. Cranial auscultation should be performed in all cases of papilledema and cranial nerve palsy.
