Background: Parkinsonism-hyperpyrexia syndrome (PHS) is a potentially life-threatening condition that occurs due to the abrupt withdrawal or significant dose reduction of antiparkinsonian medications. It presents similarly to neuroleptic malignant syndrome (NMS) and is characterized by severe rigidity, fever, autonomic instability, and altered mental status.
Case: A 62-year-old male with a 10-year history of Parkinson's disease (PD) underwent laparoscopic mesh repair for a left-sided diaphragmatic and large hiatus hernia.
