Late onset of tacrolimus-related posterior leukoencephalopathy after living donor liver transplantation

Abstract

Neurotoxicity is a well-known side effect of tacrolimus-based immunosuppression after liver transplantation. Until now, only 31 cases of immunosuppression-associated leukoencephalopathy in liver transplant recipients reported in the literature are related to tacrolimus therapy. We report a patient who developed a posterior leukoencephalopathy syndrome, secondary to tacrolimus-based immunosuppression, after living donor liver transplantation. The special features of this case are the sudden and late onset of neurologic symptoms, a persistent comatose state, and increased signal intensity in follow-up MRI.
