Clinical Case Reports

Atypical posterior reversible encephalopathy syndrome (PRES) in transplant recipients. This study describes a case of PRES in a 19-year-old male following bilateral lung and liver transplantation. The patient presented with a bilateral tonic-clonic seizure and exhibited an unconventional MRI pattern known as the “lentiform fork sign,” indicating bilateral symmetrical vasogenic edema in the basal ganglia. Management involving immunosuppressive drug modification and magnesium supplementation led to a significant clinical and neuroimaging resolution within 14 days. This case underscores the diverse manifestations of PRES, the pivotal role of neuroimaging in diagnosis, and the need for tailored management strategies in transplant recipients.
