Acoustic Neuroma Identified After Electroconvulsive Therapy in a Patient With Recurrent Major Depression and Undifferentiated Somatoform Disorder

Abstract

Little is known about the safety of electroconvulsive therapy (ECT) in patients with brain tumors, especially in patients with acoustic neuroma, which is difficult to diagnose early. For patients with somatoform disorder, physicians may alter the sensitivity to the somatic complaints, making it even more difficult to make an early diagnosis of "silent" brain tumors. This report describes a rare case involving treatment of refractory major depression and somatoform disorder that developed into increased intracranial pressure after ECT, possibly due to an undiagnosed acoustic neuroma. It is suggested that for patients with refractory major depression with somatoform disorders, the threshold of suspicion for silent tumors should be lowered and pre-ECT brain imaging study should be performed, specifically when the pattern of symptoms of the central nervous system-related somatoform syndrome changes.
