Bone scans are not generally required in the investigation of tuberculosis. The most common reason for the request is bone pain, which may precede the diagnosis of tuberculosis. The finding of multifocal areas of increased uptake on a bone scan may be due to a number of causes, the most common of which is metastatic bone disease. Therefore, there is a risk that those caused by tuberculosis may be misdiagnosed. We report six such bone scans occurring over 5 years which were found to be due to skeletal tuberculosis. Five patients were of Asian descent, four of whom had had bone biopsies confirming the presence of mycobacterium tuberculosis. The sixth patient, a Caucasian, had a bone biopsy which isolated mycobacterium bovis. Although skeletal tuberculosis is generally secondary to a primary pulmonary focus, all six patients had a normal chest X-ray.
骨扫描一般不用于结核病的检查。要求进行骨扫描最常见的原因是骨痛，骨痛可能在结核病诊断之前出现。骨扫描上发现多灶性摄取增加可能由多种原因引起，其中最常见的是骨转移瘤。因此，存在将结核引起的骨扫描结果误诊的风险。我们报告了5年内出现的6例此类骨扫描结果，发现是由骨结核所致。5例患者为亚洲血统，其中4例进行了骨活检，证实存在结核分枝杆菌。第6例患者是白种人，其骨活检分离出牛分枝杆菌。虽然骨结核通常继发于原发性肺部病灶，但所有6例患者的胸部X光检查均正常。
