A rare case of propofol-induced liver injury during modified electroconvulsive therapy in an elderly woman.

A 75-year-old woman developed depression in 2010 and was treated with oral medications at our Department of Psychiatry. Since she showed no tendency toward improvement, she underwent modified electroconvulsive therapy (mECT). Later, she developed severe liver injury that was presumably induced by the propofol used for mECT. Propofol is an intravenous anesthetic agent that reportedly can be used relatively safely in the presence of liver dysfunction. We herein report the first case of propofol-induced liver injury definitively diagnosed based on positive drug lympocyte stimulation testing (DLST).
