Background: Cerebral arteriovenous malformations (AVMs) are vascular lesions with a network of dysplastic vessels between an arterial and a venous tree with no intervening capillary bed.They most commonly present with an acute hemorrhage, seizures, or persistent headaches. Case Description:The authors report the case of a 62-year-old male who presented with diplopia for 5 days. Magnetic resonance imaging and angiography demonstrated a Spetzler-Martin Grade 2 AVM located in the right frontal operculum with deep drainage into the basal vein of Rosenthal causing ipsilateral oculomotor neuropathy. The patient underwent staged embolizations of the feeding pedicles, which were derived from the internal as well as external carotid circulation. This was followed by a right pterional craniotomy for resection of the AVM.The patient reported complete resolution of the diplopia over 4 weeks with no recurrence at the 6-month follow-up appointment. Conlusion: AVMs of the brain can present with atypical clinical symptoms that can be caused by the venous drainage pattern not the location. It is important to include vascular imaging studies in the work-up of patients who present with diplopia to rule out an AVM. Early diagnosis and treatment of the AVM can result in complete resolution of the diplopia.
