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.

Herpes simplex encephalitis (HSE) is the most common cause of infectious encephalitis worldwide. Clinical features include fever and altered mental status—symptoms that are extremely common in clinical practice and nonspecific. It is important for the clinician to recognize the signs and commence empirical antiviral agents if HSE is suspected.
