骨干肿瘤及肿瘤样病变102例影像学分析

Analysis of 102 Cases of Bone Tumors and Tumor-like Lesions in the Diaphysis of Long Bones

目的:探讨发生于长骨骨干的肿瘤及肿瘤样病变的诊断及鉴别诊断。方法:回顾总结经病理证实的102例骨干肿瘤及肿瘤样病变,分析其发病特点及影像学表现。结果:102例骨干肿瘤及肿瘤样病变中男56例,女46例,平均年龄33岁。良性肿瘤53例(其中包括肿瘤样病变33例),恶性肿瘤49例,良恶性之比约为1.08∶1。位于股骨29例,肱骨39例,胫骨33例,腓骨5例,桡骨6例,尺骨4例。病种纤维结构不良最常见,其次是转移瘤。结论:骨干肿瘤及肿瘤样发病率较低,但是病变种类繁多,其发病特点和影像学表现除具备与发生在长骨其他部位类似的共性外,也有其不同的个性,充分了解其特征,有助于提高诊断水平。

Purpose： To analyze the imaging features and improve the differential diagnosis of tumor and tumor-like lesions in the diaphysis of long bones. Methods： Clinical manifestations and imaging features of 102 pathologically confirmed cases of bone tumors and tumor-like lesions in the diaphysis of long bones were retrospectively analyzed. Results： In 102 cases, 56 were male and 46 were female. The mean age was 33 years old. Of all the cases, 53 were benign tumors （including 33 cases of tumor-like lesions）, and 49 were malignant tumors, the ratio between them was 1.08 to 1. Twenty-nine cases tumors or tumor-like lesions occurred in femoral, 39 in humerus, 33 in tibial, 5 in fibula, 6 in radius and 4 in ulna. The most common disease was fibrous dysplasia, followed with metastatic tumor. Conclusion： Though having low incidence, there are a great variety of bone tumors and tumor-like lesions in the diaphysis of long bones, they may have clinical features and imaging features in common and also with individual characteristics of their own, so knowing the characters in different sites can raise our diagnostic level.
