Sylvian cistern dermoid cyst presenting with dysgeusia

Abstract

It is rare for a patient with a dermoid cyst (DC) to present with taste dysfunction. A 58-year-old man presented with an altered sense of taste. Magnetic resonance imaging of the brain showed a mass lesion in the right insula with compression effect. The tumour was resected and was found to be a DC. The postoperative course was uneventful, and the patient resumed his usual taste sensation within the early postoperative period. To the best of our knowledge, this is the first report of a sylvian cistern DC that presented with dysgeusia.
