目的分析原发性腹膜后脂肪肉瘤患者运用CT诊断的临床效果。方法回顾性分析我院2014年2月至2016年5月60例手术病理证实的原发性腹膜后脂肪肉瘤患者的CT资料,患者均行CT平扫、三期动态增强扫描。结果 (1)肿瘤大小为9~30cm,大部分肿瘤形态为不规则,属于腹膜后间隙的肿瘤;(2)60例患者中32例的肿块典型为脂肪成分,CT值为-5~-119Hu,增强扫描发现肿块脂肪无强化,而软组织成分为轻度强化。结论运用CT诊断原发性腹膜后脂肪肉瘤,可准确的定位与判断肿瘤和临近组织的关系,能够有效的检查出高分化脂肪肉瘤与含脂肪的非高分化的脂肪肉瘤,临床应用价值极高。
Objective To analyze the clinical effect of CT diagnosis in patients with primary retroperitoneal liposarcoma. Methods The CT data of 60 patients with primary retroperitoneal liposarcoma proved by operation and pathology from February 2014 to May 2016 in our hospital were retrospectively analyzed. All patients underwent CT scan and three-phase dynamic contrast-enhanced scan. Results (1) The size of the tumor was 9 ~ 30cm, most of the tumors were irregular and belonged to the retroperitoneal space. (2) The mass of 32 cases in 60 patients was typically fat and the CT value was -5 ~ -119Hu , Enhanced scan revealed no enhancement of lump fat, soft tissue components and mild enhancement. Conclusions CT diagnosis of primary retroperitoneal liposarcoma can accurately locate and determine the relationship between the tumor and the adjacent tissue, can effectively detect the high differentiated liposarcoma and fat-containing non-differentiated liposarcoma, clinical application of very high value .
