New mania post acoustic neuroma resection: more than a coincidence

Abstract

Mood disorder is a rare complication of acoustic neuroma resection, and therefore unlikely to be listed as a possible risk on a preoperative consent form. However, the occurrence of this has been recognised since as far back as 1914. This case study reports the new presentation of mania in a 65‐year‐old woman, seven weeks after surgical removal of an acoustic neuroma. The case study explores whether the acoustic neuroma and its surgical management could be directly causative of her psychiatric disorder, or whether it simply represents a psychological trigger in a susceptible patient.
