摘　　要：目的探讨股骨近端转移性骨肿瘤的影像学表现,提高对本病的认识。方法搜集12例经手术、病理或临床确诊的股骨近端转移性骨肿瘤患者,对其影像表现进行分析。结果影像学表现可分为三型。溶骨型9例,X线表现为低密度缺损区,边界不清;MRI局部T1WI呈低信号、T2WI混杂信号改变。成骨型1例,X线表现为多发结节状高密度影,边界清,骨轮廓无改变。混合型2例,兼有溶骨和成骨性改变。原发病以肺癌为多(9/12)。男性多见(9/12)。右侧多见(8/12)。结论股骨近端转移性骨肿瘤影像学表现无明显特征,以溶骨性多见;中老年人股骨近端骨质破坏,应首先考虑转移性骨肿瘤;原发病以肺癌多见,可疑为转移性骨肿瘤病人应例行胸部影像学检查。Objective To explore and improve the image of metastasis at the close end of thighbone. Methods 12 cases of metastasis at the close end of thighbone were diagnosed by surgery, pathology or clinical information. Various image characteristics of them were analyzed. Results Metastasis at the close end of thighbone could be divided into 3 types. 9 eases as bone- dissolving were performed as low sensitivity area with unclear border in X-ray and low signal at T1WI while mixture signal at T2WI in MRI; 1 ease as bone-becoming, appeared high sensitive multi nodules with dear border and without bone shape changing in X-ray; 2 cases as mixed type included both bone-dissolving and bone-becoming. Most of the protopathies were from lung cancer （9/12） ; Most of the cases were man（9/12） and in the right（8/12）. Conclusion Most metastasis at the close end of thighbone are bone-dissolving. Metastasis should be considered firstly when destructions were discovered at the close end of thighbone in mid-old people. Most protopathies are lung cancer, and thorax imaging should be as routine check when metastasis is suspected.
