目的 探讨肩关节区域肿瘤和肿瘤样病变的影像学诊断及鉴别诊断思路.方法 回顾分析我院经手术病理证实的患有肩关节区域肿瘤或肿瘤样病变42例患者的临床及影像学资料.结果 42例患者中骨肿瘤25例,软组织肿瘤14例,关节病变3例.正确诊断29例,误诊5例,诊断不明但可明确良恶性8例.常见临床症状在辨别病变良恶性方面无显著性筹异.结论 肩关节区域肿瘤和肿瘤样病变来源复杂,种类繁多,部分病变仅可区分良恶性,合理的诊断及鉴别诊断思路有助病变的早期正确诊断.%Objective To explore imaging diagnosis and differential diagnosis method of tumors and tumor-like lesions of the shoulder girdle. Method Clinical and image datas of 42 cases with tumors or tumor-like lesions of the shoulder girdle proved by pathology were analyzed retrospectively. Results Skeletal tumors in 25 cases, soft-tissue masses in 14 cases and joint lesions in 3 cases. Correct diagnosis in 29 cases, misdiagnosis in 5 cases and difficult diagnosis in 8 cases. There was no significant correlation between clinical datas and characters of the lesions (P>0.0S). Conclusions Tumors and tumor-like lesions of the shoulder girdle are various, some of which can only be distinguished benign or maligant leisions. Reasonable imaging diagnosis and differential diagnosis method can help much to diagnose tumors and tumor-like lesions of the shoulder girdle as soon as possible.
