POSTERIOR FOSSA MENINGIOMAS PRESENTING WITH MÉNIÈRE'S-LIKE SYMPTOMS

Abstract

Abstract OBJECTIVE AND IMPORTANCE In rare cases, posterior fossa meningiomas can involve the endolymphatic sac. Such involvement can result in endolymphatic hydrops and a constellation of symptoms suggestive of Ménière's disease. The diagnosis and management of patients with these tumors is discussed. CLINICAL PRESENTATION Three patients, each of whom presented with symptoms consistent with Ménière's disease, were found to have posterior fossa meningiomas limited to the dura overlying the endolymphatic sac. INTERVENTION All 3 patients were diagnosed by magnetic resonance imaging and underwent complete surgical resection. In all cases, the symptoms resolved after tumor removal. CONCLUSION Clinicians should have a degree of suspicion of posterior fossa meningioma when patients present with symptoms suggestive of Ménière's disease. Failure to do so may result in delayed diagnosis or worse outcomes for an otherwise treatable tumor.
