摘要
目的:分析股骨近段骨肿瘤的临床特征及影像学表现,以提高对股骨近段骨肿瘤的认知及疾病诊断水平。方法:回顾2010年至2016年本院收治的资料完整的91例股骨近段骨肿瘤。总结分析患者的性别、年龄、病理类型及影像学表现。两名放射科诊断医师分别对DR、CT、MRI诊断骨肿瘤的价值进行评价。结果:原发肿瘤76例,转移瘤15例。男53例,女38例,年龄4~83岁,平均34.43岁。良性骨肿瘤47例,占51.65%;中间型骨肿瘤20例,占21.98%;恶性骨肿瘤24例,占26.37%。良性肿瘤平均发病年龄29(4~60)岁,常见病种有纤维结构不良、单纯骨囊肿。中间型肿瘤平均发病年龄为21(4~40)岁,常见病种有动脉瘤样骨囊肿、软骨母细胞瘤;恶性肿瘤平均发病年龄为59(36~83)岁,转移瘤最常见。CT和MRI骨肿瘤的诊断符合率均高于DR(P<0.05),CT和MRI的诊断符合率没有统计学意义(P>0.05)。结论:股骨近段骨肿瘤中,良性及中间型骨肿瘤多见,以未明确肿瘤性质的肿瘤为主;恶性骨肿瘤以转移瘤最多。CT和MRI股骨近段骨肿瘤诊断价值优于DR。
Objective: To deepen the understanding of bone tumours in proximal femur and to improve the diagnosis by analyzing the clinical and radiological features of bone tumours in proximal femur. Methods: Data of our tumor database were reviewed. There were 91 cases of bone tumours in proximal femur between 2010 and 2016. The pathological types,age and gender of patients,and radiological features were recorded. Two radiologists evaluated the DR,CT,MRI in diagnosing bone tumors according to inclusion and evaluation criteria. Results: There were 76 cases of primary tumors and 15 cases metastatic tumors. 53 were male and 38 were female. Age of onset varied from 4 to 83 years,the mean age was 34. 43 years old. There were 47 cases( 51. 65%) of benign tumors,20 cases( 21. 98%) of intermediate tumors and 24 cases( 26. 37%) of malignancy. The mean age of benign tumors was 29 years( range: 4 ~60 years). The most common tumor types were fibrous dysplasia and simple bone cyst. The mean age of intermediate tumors was 21 years( range: 4 ~ 40 years). The most common tumor types were aneurysmal bone cyst and chondroblastoma. The mean age of malignancy was 59 years( range: 36 ~ 83 years). The most common tumor types was metastasis. The CT and MRI in the diagnosis of bone tumor coincidence rate were higher than DR( P < 0. 05). There was no statistical significance for diagnostic accordance rate of CT and MRI( P > 0. 05). Conclusion: Benign and intermediate tumors are more common than the malignant ones among proximal femur tumors. Tumor of undefined neoplastic nature are common tumor type,and metastasis is the most common malignant tumor. CT and MRI in the diagnosis value of bone tumors are superior to the DR.
