目的　分析多部位骨关节结核的X线表现 ,以提高对该病的诊断能力。方法　 5例均经病理证实 ,男 1例 ,女 4例 ,年龄15～ 5 6岁。均拍摄病变部位X线平片 ,其中 1例行椎管造影术 ,2例行局部活检术 ,3例行局部病灶清除术。结果　 5例病例均累及多个部位 ,3～ 5个不等 ,其中同时累及长管状骨和短管状骨 3例 ,累及扁骨和椎体 1例 ,累及长管状骨、扁骨和椎体 1例。 3例同时累及长管状骨和短管状骨者为同侧发病 ,而同时累及扁骨和椎体者 2例为双侧发病。X线平片表现为溶骨性骨质破坏区 ,呈圆形、椭圆形或不规则形 ,部分边缘硬化 ,伴周围软组织肿胀。结论　多部位骨关节结核累及的部位多 ,临床表现和X线征象有一定的特点 ,但确诊需行病理检查 Objective To analyze the X-ray findings of multi-site osteoarticular tuberculosis in order to improve the diagnosis of the disease. Methods 5 cases were confirmed by pathology, 1 males and 4 females, aged 15 to 56 years. The lesions were taken X-ray films, including 1 case of spinal angiography, 2 cases of local biopsy, 3 cases of local lesion removal. Results All the 5 cases involved multiple sites ranging from 3 to 5, including 3 cases involving long and short tubular bones, 1 case involving oblate bone and vertebral body, involving long tubular bone, flat bones and vertebral body 1 example. 3 cases involving both long and short tubular bones were ipsilateral, while 2 cases involving both oblate and vertebral body were bilateral. X-ray film showed osteolytic bone destruction area, was round, oval or irregular shape, part of the edge of the sclerosis, with surrounding soft tissue swelling. Conclusion Multi-site osteoarthritis tuberculosis involving parts, clinical manifestations and X-ray findings have some characteristics, but the diagnosis required pathological examination
