Abstract

Primary intracranial melanomas are rare, especially in the primary cerebellopontine angle. We describe a patient with a presumed jugular foramen meningioma that was found to be of melanotic origin at surgery. We followed this 26-year-old woman with mild ataxia with serial imaging for 18 months after the initial discovery of a cerebellopontine angle extra-axial mass. She developed worsening symptoms of ataxia, dysphagia, and right-sided hearing loss. Magnetic resonance imaging showed an interval increase in size of the mass. The lesion was thought to be a meningioma with a dural tail that extended into the jugular foramen and hypoglossal canal. She underwent preoperative angiography and attempted tumor embolization, followed by resection via a transcochlear infratemporal approach. At surgery the lesion was found to be heavily pigmented. Pathological analysis was consistent with a low-grade melanoma. No primary extracranial site was identified. One year after surgery the patient remains free of systemic disease or recurrence.
