Hypermetabolic Syndrome and Dyskinesia After Neurologic Surgery for Labrune Syndrome: A Case Report.

A 20-year-old man with a rare neurodegenerative disease developed hypermetabolic symptoms with dyskinesia after a third ventriculostomy for hydrocephalus. The initial presentation was concerning for an acute dystonic reaction after metoclopramide was administered for nausea. He concurrently developed hypermetabolic symptoms, including hyperthermia, tachycardia, and a lactic acidosis. The diagnosis was broadened to include neuroleptic malignant syndrome, serotonin syndrome, and malignant hyperthermia. Although perhaps less intellectually satisfying but more true to clinical reality, we did not isolate a single diagnosis but treated effectively all 3 with dantrolene sodium and benzodiazepine.
