【摘要】：目的分析浸潤性腎盂癌的CT增強(qiáng)表現(xiàn),旨在提高診斷正確率。方法回顧性分析經(jīng)病理證實(shí)的20例浸潤性腎盂癌的CT影像表現(xiàn)特點(diǎn),術(shù)前均行多排螺旋CT及CTU掃描。根據(jù)影像學(xué)圖像上腎盂內(nèi)腫塊形態(tài)及腎實(shí)質(zhì)浸潤程度將本組病例分為Ⅰ型:腫塊浸潤型,腎盂內(nèi)明顯腫塊,病變隆起高度≥橫徑,腎竇脂肪受侵,伴或不伴腎實(shí)質(zhì)浸潤;Ⅱ型:淺表浸潤型,腎盂內(nèi)扁平型腫塊,病變隆起高度橫徑,腎竇脂肪消失,腎實(shí)質(zhì)受侵,扁平的腎盂腫塊、增厚腎盂壁及腎實(shí)質(zhì)融合;Ⅲ型:深部浸潤型,向腎盂外浸潤生長,腎盂內(nèi)無明顯腫塊,增厚的腎盂壁、腫塊及腎實(shí)質(zhì)融合,常伴腫大淋巴結(jié)、鄰近血管及輸尿管受侵。結(jié)果 20例中,16例術(shù)前診斷為腎盂癌,2例誤診為腎癌,1例誤診為急性腎盂腎炎,尚有1例誤診為集合管癌,經(jīng)病理診斷全部為浸潤性腎盂癌。Ⅰ型4例,Ⅱ型4例,Ⅲ型12例。結(jié)論浸潤性腎盂癌不僅僅是腎盂內(nèi)腫塊伴腎竇脂肪和腎實(shí)質(zhì)浸潤,部分腫瘤、腎盂、腎實(shí)質(zhì)融合,部分腫瘤腎盂外浸潤明顯而腎盂壁增厚相對(duì)不顯著。認(rèn)識(shí)浸潤性腎盂癌不同表現(xiàn)有助于提高診斷準(zhǔn)確性。
[Abstract]:Objective to analyze CT enhancement features of invasive renal pelvis carcinoma and to improve the diagnostic accuracy.Methods the CT features of 20 cases of invasive renal pelvis carcinoma proved by pathology were retrospectively analyzed. All cases were examined with multi-slice spiral CT and CTU before operation.According to the shape of renal pelvis mass and the degree of renal parenchyma infiltration, the patients were classified into type 鈪，
