Bone scintigraphy was performed in a healthy 30-year-old man because of post-traumatic heel pain. The scintigraphy displayed a bilateral increased uptake of 99mTc-MDP in the pectoral muscles and triceps brachii. Further extensive investigations including muscle biopsy were normal and excluded diagnoses such as polymyositis, myositis ossificans or amyloidosis. The abnormalities were in fact explained by physical exercise performed a few hours prior to the radionuclide scan. This was confirmed by the absence of these changes on a second bone scan performed 3 months later. This case shows that muscle exercise should be kept in mind as a cause of skeletal muscle uptake of bone-seeking agents, with the view to avoid unnecessary investigations.
一名30岁健康男性因创伤后足跟疼痛接受了骨闪烁扫描。扫描显示双侧胸肌和肱三头肌对99mTc-MDP摄取增加。包括肌肉活检在内的进一步广泛检查均正常，排除了多发性肌炎、骨化性肌炎或淀粉样变性等诊断。这些异常实际上是由放射性核素扫描前几小时进行的体育锻炼所致。3个月后进行的第二次骨扫描未出现这些变化，证实了这一点。该病例表明，应将肌肉锻炼视为骨骼肌摄取亲骨性药物的一个原因，以免进行不必要的检查。
