目的分析髌骨肿瘤的病种分布及其影像学表现。资料与方法回顾性分析本院自1976年至2008年经病理证实的髌骨肿瘤患者资料,分析髌骨骨肿瘤的发病情况及影像学表现。结果髌骨肿瘤共26例,男女比例17∶9。以软骨母细胞瘤(8例)最为多见,其次为骨巨细胞瘤(4例),髌骨的恶性肿瘤少见。影像学表现中,软骨母细胞瘤、骨巨细胞瘤,甚至纤维结构不良均可表现为膨胀性生长,有时难以区分。但软骨母细胞瘤倾向于病灶小,边缘硬化,有时见病灶内钙化。结论髌骨肿瘤以良性为主,恶性肿瘤少见;综合分析髌骨不同肿瘤的发病率及其影像特征,有助于提高髌骨肿瘤的诊断正确率。
Objective To analyze the distribution of disease types and imaging features of patellar tumors. Materials and Methods Retrospective analysis of patients with pathologically confirmed patellar tumors in our hospital from 1976 to 2008 to analyze the incidence of patellar bone tumors and imaging findings. Results A total of 26 cases of patellar tumors, male to female ratio of 17: 9. Chondroblastoma (8 cases) is the most common, followed by giant cell tumor (4 cases), the rare patella cancer. Imaging findings, chondroblastoma, giant cell tumor of bone, and even fibrous dysplasia can be expressed as swollen growth, and sometimes difficult to distinguish. Chondroblastoma, however, tends to be small, marginally hardened, and sometimes see intralesional calcification. Conclusions Patellar tumors are mainly benign and rare malignant tumors. Comprehensive analysis of the incidence of patellar tumors and their imaging features will help to improve the diagnostic accuracy of patella tumors.
