Intense muscle uptake of Tc-99m MDP and Ga-67 citrate in massive rhabdomyolysis.

A 6-year-old boy had an Addisonian crisis with hyponatremic shock and required resuscitation after cardiac arrest. Severe renal failure necessitated continuous dialysis. Rhabdomyolysis was identified because of myoglobinuria and gross elevation of creatinine kinase. In the course of his treatment, bone infection was suspected. A bone scan with Tc-99m MDP showed intense uptake in numerous major muscle groups throughout the body in keeping with massive rhabdomyolysis. Similar gross muscle uptake of Ga-67 citrate was less expected. In an additional bone scan obtained 15 days later, the MDP uptake showed less intense accumulation.
