摘　　要：目的:分析股骨近端良性骨肿瘤与肿瘤样病变的影像学特征表现,探讨其临床意义。方法:回顾性分析56例经手术病理证实的股骨近端良性骨肿瘤和肿瘤样病变的影像学特征表现。全部病例均行X线检查,其中30例同时行CT检查,25例行MRI检查。结果:骨囊肿15例,骨纤维结构不良11例,骨软骨瘤6例,动脉瘤样骨囊肿5例,骨巨细胞瘤5例,软骨母细胞瘤和骨母细胞瘤各3例,骨化性纤维瘤2例,非骨化性纤维瘤1例,纤维组织细胞瘤1例,内生软骨瘤1例,韧带样纤维瘤1例,软骨粘液样纤维瘤1例,骨样骨瘤1例。所有病例在病变部位、数目、大小、边界、内部结构、软组织改变及病理性骨折方面具有一些共性及特性。结论:股骨近端良性骨病种类繁多,以骨纤维结构不良和骨囊肿为好发病种,多种影像学方法的联合使用在诊断和鉴别诊断中具有重要作用,有利于临床选择治疗方式及评判预后。Objective：To evaluate imaging findings of benign osteopathy in proximal femur and to optimize pre-opera- tive staging. Methods： 56 cases of histologically confirmed benign osteopathy in proximal femur were involved. Radiogram of the hip joint was taken for all patients with additional examination of CT in g2 patients and MRI in 21 patients. Results： There were simple bone cyst in 15 cases,fibrous dysplasia in 11 cases,osteochondroma in 6 cases,aneurysmal bone cyst in 5 cases,giant cell tumor in 5 cases, chondroblastoma in 3 cases, osteoblastoma in 3 cases, ossifying fibroma in 2 cases, non-os- sifying fibroma in 1 case, benign fibrous histiocytoma in 1 case, enchondroma in 1 case, desmoplastic fibroma in 1 case, chon- dromyxoid fibroma in 1 case and osteoid osteoma in 1 case. All these cases had common characteristics in terms of the lesion number, size, boundary,internal structure, soft tissue reaction and pathologic fracture. Conclusion： There are different kinds of benign osteopathy in proximal femur. Simple bone cyst and fibrous dysplasia are more frequently seen. More than one im- aging methods used in combination play an important role in the diagnosis and differential diagnosis, and will be conducive to the choice of treatment and evaluation of prognosis.
