[A case of unusually muscle localization of 99mTc-hydroxy methylene diphosphonate scintigraphy in a patient with acute rhabdomyolysis].

: A 85-year-old man was admitted with a history of right upper arm pain following trauma. Laboratory studies included an initial CPK level of 5,385 IU/liter. Other laboratory values were GOT, 114 IU/L; LDH, 701 IU/L; myoglobin, 1,100 ng/ml; aldolase, 13.8 IU/L. The patient was presumed to have have rhabdomyolysis. A 99mTc-hydroxy methylene diphosphonate (99mTc-HMDP) scan revealed an increased uptake in the right shoulder area. 99mTc-HMDP scan is a sensitive indicator of local skeletal muscle injury in rhabdomyolysis.
