OBJECTIVE: A vertebral artery aneurysm mimicking a contralateral cerebellopontine angle tumor is described. This is only the second reported case of this in the literature. STUDY DESIGN: Case report. SETTING: Radcliffe Infirmary, Oxford, United Kingdom. PATIENT: Seventy-year-old female patient who presented with a gradually deteriorating right-sided sensorineural hearing loss and a right facial palsy. INTERVENTIONS: Magnetic resonance imaging scan and computed tomography angiography with three-dimensional reconstruction followed-up by endovascular coiling of a vertebral artery aneurysm. MAIN OUTCOME MEASURE: Deterioration in neurologic status. RESULTS: Satisfactory recovery, and at 3 months, the patient is well with no deterioration in facial nerve function. CONCLUSION: Imaging by means of computed tomography angiography complements the standard magnetic resonance imaging scan in the rare event of an aneurysm at the cerebellopontine angle. Endovascular coiling occlusion is a recognized and effective way of managing intracranial aneurysms at the cerebellopontine angle.
