【摘要】：目的 :探讨肾透明细胞癌的MSCT表现,以提高其诊断水平。方法 :回顾性分析我院经手术病理证实的23例肾透明细胞癌的MSCT表现,所有患者均行平扫、皮髓交界期、实质期和排泄期增强扫描。结果:23例中,单发21例,多发2例(1例为单侧2个病灶,1例为双侧7个病灶)。23例共30个病灶,左侧10个,右侧20个。肿瘤呈圆形或类圆形,直径1~12 cm,平均4.6cm,其中≤3 cm 12个。CT平扫病灶呈等密度4个,囊性低密度3个,混杂密度23个;钙化6个。增强扫描:除2个较小肿瘤呈均匀强化外,28个强化不均匀;皮髓质期25个病灶明显强化,强化最明显区高于邻近皮质者15个,相似或略低于邻近皮质者10个;实质期肿瘤强化程度降低;排泄期肿瘤与肾实质相比呈明显低密度,病灶边界更清楚;25个病灶内见不同程度坏死、囊变。13个有假包膜。3个囊性肾透明细胞癌,平扫病灶呈囊状,2个表现如单纯性肾囊肿,1个可见网格状分隔;增强扫描1个肾透明细胞癌明显囊变,囊壁及分隔明显不规则强化;2个多房囊性肾透明细胞癌分隔不规则强化。结论:肾透明细胞癌血供丰富,瘤内可有出血、坏死、囊性变、钙化及假包膜,CT表现具有一定特征,大多可准确诊断。
[Abstract]:Objective: to investigate MSCT findings of renal clear cell carcinoma (RCC) and to improve its diagnostic level. Methods: MSCT findings of 23 cases of renal clear cell carcinoma confirmed by surgery and pathology were retrospectively analyzed. Results among 23 cases, 21 cases were single, 2 cases were multiple (1 case was unilateral 2 lesions, 1 case was bilateral 7 lesions). 23 cases had 30 lesions, 10 lesions on the left side and 20 lesions on the right side. The tumors were round or round, with a diameter of 1 ~ 12 cm with an average of 4.6 cm. Among them, 12 lesions 鈮，
