title: Neuromyopathy in malignant hyperthermia.
abstract: A 31-year old male developed malignant hyperthermia (MH) during the initial minutes of Halothane induction. CPK rose to 6120 U/ml and decreased to normal levels as the patient became afebrile over a 10 day period of cooling measures and metabolic management. Muscle weakness, predominantly proximal and depressed deep tendon reflexes were found upon examination during convalescence. Muscle biopsy showed neurogenic changes characterized by fiber type grouping and targetoid fibers. CPK was elevated in one of the patient's children. This case supports the view of underlying hereditary neuromyopathy in MH.
