摘　　要：目的探讨腹膜后去分化脂肪肉瘤(DDL)的CT影像特点与诊断价值。方法对照病理,回顾性分析3例经手术及病理证实的腹膜后去分化脂肪肉瘤的CT表现特点。结果 3例腹膜后去分化脂肪肉瘤中,单发2例,多发伴高分化脂肪肉瘤1例;CT平扫均表现为软组织肿块中存在明确脂肪成分,二者分界清楚,脂肪含量不一,但均较少且位于肿块周边区域。增强扫描肿瘤实质成分动脉期呈轻至中度强化,静脉期呈渐进性强化。其中1例于术后7个月复发,再次手术后1.5个月再次复发,1例于术后2个月复发,1例术后1个月随访未见复发。结论腹膜后去分化脂肪肉瘤的CT特征有助于活体诊断和临床治疗方案的选择。Objective To investigate the value of CT in the diagnosis of retroperitoneal dedifferentiated liposarcoma. Methods Comparing with pathology, the CT features of 3 cases with surgery and pathologically proved retroperitoneal dedifferentiated liposarcoma were retrospectively analyzed. Results Among the 3 cases of dedifferentiation liposarcoma after peritoneal, there were 2 cases of single lesions and 1 case of multiple lesions dedifferentiation liposarcoma with well differentiated liposarcoma. CT plain scan was characterized by distinct fat component in soft tissue, boundary clearly, but with varies fat content, located in the imnp of the peripheral areas. The soft tissues were mild and moderate enhanced in arterial enhancement, gradual aggrandizement in venous phase. 1 case with recurrence after 7 months and recurrence again after 1.5 months, 1 case with recurrence after 2 months, 1case with no recurrence after 1 month in follow-up. Conclusion The CT features of retroperitoneal dedifferentiated liposarcoma can benefit to the vivo diagnosis and strategy of clinical treatment.
