Many reasons could lead to abnormal increased extraosseous tracer uptake on 99mTc-MDP bone scintigraphy. A 75-year-old man was referred a bone scintigraphy to evaluate his chest pain. The images revealed rib fractures. In addition, increased MDP activity in the muscle of the lower extremities was noted. The abnormal increased uptake in the muscles was likely related to the arterial thromboses revealed by vascular ultrasonography. The patient received interventional embolectomy.
