title: Severe rhabdomyolysis with good recovery in a patient with head injury: case report.
abstract: OBJECTIVE
  We report a case of head injury, in which a hyperosmolar state evolved during the course of treatment, complicated by severe rhabdomyolysis and acute renal failure, which subsequently resulted in a good recovery after intensive supportive treatment. To our knowledge, such high levels of creatine kinase in a patient with head injury and rhabdomyolysis have not been reported.
  
  
  METHODS
  A 19-year-old male patient with head injury sustained a compound fracture of the frontal region. He received a hyperosmolar agent to treat brain edema and developed a hyperosmolar state and diabetes insipidus 1 day after the accident. There were no obvious associated injuries at physical examination. After admission to the intensive care unit, the patient developed myoglobinuria and rhabdomyolysis; serum creatine kinase was elevated to a peak of 650,000 IU/L. Four days later, acute renal failure was noted. The patient's myoglobinuria and rhabdomyolysis gradually declined, and he eventually recovered from acute renal failure after supportive treatment and dialysis.
  
  
  CONCLUSIONS
  We postulate that the hyperosmolar state of the patient was the major cause of his severe rhabdomyolysis. Associated hypokalemia and hypophosphatemia are also predisposed to rhabdomyolysis. The most serious complication in rhabdomyolysis is acute renal failure, but most patients who receive supportive treatment and can survive despite the complications can expect to have normal renal function restored.
