2例透明细胞软骨肉瘤的误诊分析

An analysis of two misdiagnoses of clear cell chondrosarcoma

目的通过对误诊病例分析,探讨透明细胞软骨肉瘤影像学特征及其鉴别诊断方法。方法对两例透明细胞软骨肉瘤临床、影像及病理资料作系统整理并分析。结果两例肿瘤均位于长骨骨端,影像学似良性肿瘤表现,早期准确的影像学诊断非常困难,需影像、临床及病理密切结合。鉴别诊断结果为:浸润性骨巨细胞瘤与动脉瘤样骨囊肿。结论透明细胞软骨肉瘤影像学趋向良性肿瘤表现,生物学行为却为恶性,需采用广泛性切除手术方式治疗,因此早期、正确的影像学诊断至关重要。

Objective To study the imaged features of clear cell chondrosarcoma through the analysis of two misdiagnoses of patients and put forward the correct diagnosis. Methods To systematically re-arrange and analyze clinical, imaged and pathological data of two patients suffering from clear cell chondrosarcoma. Results The cancer which is suspected to be a benign tumor from the perspective of imaged performance and growing in the two patients are located at the end of their long bones. The difficulty to diagnose of such early cancer accurately through imaged makes it necessary to have an image, clinical and pathological combination for a accurate diagnosis. The differential diagnosis proved that the benign tumor is an invasive giant cell tumor and aneurysm sample bone cyst. Conclusion Early and correct image diagnosis of clear cell chondrosarcoma is the key to the treatment of chondrosarcoma which tends to be benign tumor from the perspective of image but biologically malignant.
