The Journal of ECT: March 2009 - Volume 25 - Issue 1 - p 64-66 doi: 10.1097/YCT.0b013e3181729268 Buy Metrics Abstract Electroconvulsive therapy (ECT) has been frequently considered relatively contraindicated in patients with space-occupying lesions in the brain. After the 7 cases available in the literature, we describe the safe use of ECT in a depressive patient with arachnoid cyst. We provide a comprehensive review on this clinical association, and we conclude that even if the few data available are reassuring, careful neurological evaluation before the ECT treatment is indicated. © 2009 Lippincott Williams & Wilkins, Inc.
