Electroconvulsive therapy (ECT) is considered relatively contraindicated in patients with intracranial space-occupying lesions. A 53-year-old male presented with a 5-year history of medication-refractory major depressive disorder. Brain imaging findings suggested the presence of a ruptured dermoid cyst in the transverse sinus and a calcified meningioma in the temporal lobe sulcal space. There was no evidence of mass effect. Neurofibromatosis was the only other clinical condition present. The patient had no clinical neurological deficits. Since the depression was severe and he was suicidal, ECT was advised. There was a substantial improvement after four bilateral and then eight right unilateral brief-pulse ECTs administered on alternate days, thrice weekly. There were no complications associated with ECT. The treatment gains were maintained with maintenance antidepressant medication at a 1-year follow-up. This is probably the first reported case of the use of ECT in a medication-refractory, severely depressed patient with a ruptured intracranial dermoid cyst and with a calcifying meningioma. The results testify to the safety of ECT even in high-risk patients. [ABSTRACT FROM AUTHOR]
