[Rhabdomyolysis and kidney failure in hypothyroidism].

Muscular disorders are usual in hypothyroidism, but hypothyroid myopathy is most often limited to myalgias, muscle stiffness and cramps with sometimes elevated levels of muscle enzymes. We report a case of acute renal failure related to rhabdomyolysis, which complicated hypothyroïd myopathy. Thyroid hormone replacement therapy improved thyroid and renal function, and reversal rhabdomyolysis. Hypothyroidism appears to be an authentic cause of rhabdomyolysis and should be eliminated in all patients with serum muscle enzyme increase.
