目的　分析股骨上段骨肿瘤及肿瘤样病变的平片与CT表现 ,旨在提高对该区病变的诊断水平。方法　 2 4例经手术病理证实的病例 ,回顾性分析平片与CT表现 ,并与手术病理结果相对照。结果　 19例 ( 79.2 % )包括转移性肿瘤 6例 ,骨巨细胞瘤 4例 ,骨纤维异常增殖症 4例 ,骨囊肿 3例 ,软骨肉瘤、骨肉瘤各 1例 ,术前诊断与手术病理结果一致。 5例 ( 2 0 .8% )包括不典型骨肉瘤、海绵状血管瘤、软骨黏液样纤维瘤、骨恶性纤维组织细胞瘤及淋巴瘤各 1例 ,平片与CT表现不典型 ,术前定性诊断与手术病理结果不完全一致。结论　平片是股骨上段骨肿瘤及肿瘤样病变的主要检查方法。CT对病灶内部细致观察及显示软组织侵犯较平片为好。局部病灶活检是确诊的有效方法 Objective To analyze the plain film and CT findings of the upper femur bone tumors and tumor-like lesions in order to improve the diagnosis of lesions in the area. Methods Twenty-four cases confirmed by surgery and pathology were retrospectively analyzed for plain film and CT findings and compared with the results of surgical pathology. Results 19 (79.2%) patients included 6 cases of metastatic tumor, 4 cases of giant cell tumor of bone, 4 cases of osteofibroma dysplasia, 3 cases of bone cyst, 1 case of chondrosarcoma and osteosarcoma. The results of preoperative diagnosis and surgical pathology Consistent. Five cases (20.8%) included atypical osteosarcoma, cavernous hemangioma, cartilage myxoid fibroma, malignant fibrous histiocytoma and lymphoma in 1 case, plain film and CT were not typical, preoperative qualitative Diagnosis and surgical pathology results are not exactly the same. Conclusion Plain film is the main method of examination of upper femur bone tumor and tumor-like lesions. CT on the lesion within the detailed observation and show that soft tissue invasion is more flat than good. Local lesion biopsy is an effective method of diagnosis
