【摘要】：目的 :探討腎透明細(xì)胞癌的MSCT表現(xiàn),以提高其診斷水平。方法 :回顧性分析我院經(jīng)手術(shù)病理證實的23例腎透明細(xì)胞癌的MSCT表現(xiàn),所有患者均行平掃、皮髓交界期、實質(zhì)期和排泄期增強(qiáng)掃描。結(jié)果:23例中,單發(fā)21例,多發(fā)2例(1例為單側(cè)2個病灶,1例為雙側(cè)7個病灶)。23例共30個病灶,左側(cè)10個,右側(cè)20個。腫瘤呈圓形或類圓形,直徑1~12 cm,平均4.6cm,其中≤3 cm 12個。CT平掃病灶呈等密度4個,囊性低密度3個,混雜密度23個;鈣化6個。增強(qiáng)掃描:除2個較小腫瘤呈均勻強(qiáng)化外,28個強(qiáng)化不均勻;皮髓質(zhì)期25個病灶明顯強(qiáng)化,強(qiáng)化最明顯區(qū)高于鄰近皮質(zhì)者15個,相似或略低于鄰近皮質(zhì)者10個;實質(zhì)期腫瘤強(qiáng)化程度降低;排泄期腫瘤與腎實質(zhì)相比呈明顯低密度,病灶邊界更清楚;25個病灶內(nèi)見不同程度壞死、囊變。13個有假包膜。3個囊性腎透明細(xì)胞癌,平掃病灶呈囊狀,2個表現(xiàn)如單純性腎囊腫,1個可見網(wǎng)格狀分隔;增強(qiáng)掃描1個腎透明細(xì)胞癌明顯囊變,囊壁及分隔明顯不規(guī)則強(qiáng)化;2個多房囊性腎透明細(xì)胞癌分隔不規(guī)則強(qiáng)化。結(jié)論:腎透明細(xì)胞癌血供豐富,瘤內(nèi)可有出血、壞死、囊性變、鈣化及假包膜,CT表現(xiàn)具有一定特征,大多可準(zhǔn)確診斷。
[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，
