摘要
目的：探讨CT及MRI对腹壁隆突型皮肤纤维肉瘤的诊断价值。方法：收集2012—2014年我院5例经手术及病理证实的来源腹壁的隆突型皮肤纤维肉瘤患者的MRI及CT资料。结果：CT表现为稍低密度，边界清楚，MRI表现为皮下脂肪内规则肿块，边界清楚，在T1WI图像上呈低信号，T2WI图像上呈高信号。MRI和CT增强扫描病灶均呈均匀明显强化。结论：腹壁隆突型皮肤纤维肉瘤具有单发、病灶边界清楚、均匀明显强化等影像学特征，结合临床特征及影像学特点可以做出明确诊断。
Abstract
Objective: To explore the diagnostic value of CT and MRI in dermatofibrosarcoma protuberans on abdominal walls. Methods: The MRI and CT image data of five patients with dermatofibrosarcoma protuberans on abdominal walls confirmed by operation and pathology were collected in our hospital from 2012 to 2014. Results: Masses with slightly low or equal homogeneous density and clear boundaries were shown on CT images. Subcutaneous regular fat masses with clear boundaries, which showed low signals on T1WI images and high signals on T2WI images, were shown on MRI. The lesions with homogeneous and obviously enhanced appearance were shown on contrasted enhancement MRI and CT. Conclusion: The dermatofibrosarcoma protuberans has characteristics: single lesion with clear boundary, uniform significantly enhancement on abdominal walls. Combination with clinical features and imaging characteristics may make a definite diagnosis.
