[Paraneoplastic rhabdomyolysis].

A 49-year-old female patient presented with decline of general health and muscle pain. Laboratory findings showed a combination of rhabdomyolysis and severe hypokalemia. Symptoms improved with potassium supplementation. Hyperaldosteronism was identified as the underlying cause of the hypokalemia. Sonography revealed an adrenal mass that was diagnosed as adrenal carcinoma following surgical removal. Hypokalemia is a rare cause of rhabdomyolysis and should prompt consideration of hyperaldosteronism.
