[Chronic rhabdomyolysis disclosing mitochondriopathy and malignant hyperthermia susceptibility].

We report the case of a 24-year old man with a recent history of unexplained chronic rhabdomyolysis. The muscle biopsy showed a mitochondrial myopathy associated with a malignant hyperthermia susceptibility. These two abnormalities can be implied in the recurrent rhabdomyolytic phenomenon, with a possible potentialisation. The therapeutic approach is discussed.
