摘　　要：目的总结骨原发性平滑肌肉瘤的X线、CT表现,提高对其影像学认识。资料与方法搜集资料完整且经病理证实的骨原发性平滑肌肉瘤10例,回顾性分析其X线、CT表现。结果股骨远侧骨端3例,胫骨近侧骨端2例,胫骨干、股骨干、锁骨、骶骨和髂骨嵴各1例,均为单发病灶,其中溶骨型3例,囊肿型3例,混合型4例。6例见骨梗死灶,4例见骨膜反应,4例合并大小不等的软组织肿块影,1例合并病理性骨折。结论骨原发性平滑肌肉瘤主要发生于长骨骨端,以膝关节附近最为多见,多侵犯单骨。溶骨性骨质破坏区内或周围软组织肿块出现骨梗死灶,有助于对骨平滑肌肉瘤的诊断。Objective To summary the X-ray and CT findings of primary leiomyosarcoma of bone（PLB）. Materials and Methods Ten cases of PLB proved by surgery and pathology were collected in our study. The X-ray and CT findings were retrospectively analyzed. Results Solitary lesion was detected in every case. The lesions were located at distal femorial extremities （3 cases）,proximal tibia extremities （2 cases）,femoral shaft （1 case）,tibial shaft （1 case）,clavicle （1 case）,sacrum （1 case） and crista iliaca （1 case）. Osteolytic bone destruction was found in 3 cases,cystic bone destruction in 3 cases and mixed bone destruction in 4 cases. Bone infarction was found in 6 cases,periosteal reaction in 4 cases,soft tissue mass in 4 cases and pathologic fracture in 1 case. Conclusion PLB mainly involved long tubular bones,especially nearby knee joint. The features of bone infarction in osteolytic destruction and/or soft tissue mass contribute to the diagnosis of PLB.
