【摘要】：目的觀察不同組織學(xué)分型胸腺上皮性腫瘤(TET)的MSCT表現(xiàn)特征。方法回顧性分析108例經(jīng)手術(shù)或穿刺病理證實(shí)TET的術(shù)前CT表現(xiàn),并與2004年WHO分型標(biāo)準(zhǔn)比較,探討不同組織類型TET的CT特征。結(jié)果 108例中,A型胸腺瘤3例,AB型30例,B1、B2、B3型分別為15例、29例、9例,胸腺癌22例。合并重癥肌無力(MG)者32例(32/108,29.63%)。合并MG患者中,B型胸腺瘤者明顯高于其他分型[45.28%(24/53)vs 14.55%(8/55),χ2=12.23,P0.001]。胸腺癌最大徑5cm者多于胸腺瘤[72.73%(16/22)vs 44.19%(38/86),χ2=5.708,P=0.017]。A、AB、B1型胸腺瘤多呈圓形或卵圓形,B2型多呈分葉狀,胸腺癌形態(tài)多不規(guī)則(χ2=32.917,P0.001)。B3型胸腺瘤和胸腺癌壞死囊變發(fā)生例數(shù)分別為6例和10例,明顯高于其他胸腺瘤[51.61%(16/31)vs 24.68%(19/77),2χ=7.322,P=0.007]。與B1、B2、B3型相比,A、AB型、胸腺癌強(qiáng)化程度以中度強(qiáng)化為主[58.18%(32/55)vs 30.19%(16/53),2χ=11.820,P=0.001]。胸腺癌影像分期多為Ⅲ期,與其他型分布比較差異有統(tǒng)計(jì)學(xué)意義[54.55%(12/22)vs 13.95%(12/86),2χ=38.958,P0.001]。影像分期與臨床分期有相關(guān)性(r=0.548,P0.01)。結(jié)論不同組織類型TET的CT表現(xiàn)具有一定特征性。CT可在一定程度預(yù)測(cè)TET組織學(xué)類型,提示臨床分期及預(yù)后。
[Abstract]:Objective to observe the MSCT features of thymic epithelial tumors with different histological types. Methods the preoperative CT findings of 108 cases of TET proved by operation or puncture pathology were retrospectively analyzed and compared with the WHO classification standard in 2004. The CT features of different tissue types of TET were discussed. Results among 108 cases of Thymoma, there were 3 cases of type AB thymoma and 30 cases of type B _ 1 B _ 2 and B _ 3, which were 15 cases and 29 cases, respectively, and 22 cases of thymic carcinoma. 32 cases (32 / 108%) were complicated with myasthenia gravis (MG) (29.63%). The rate of type B thymoma complicated with MG was significantly higher than that of other types [45.28% (24 / 53) vs 14.55% (8 / 55), 蠂 ~ 2 + 12.23% P0.001]. The maximum diameter of 5cm in thymic carcinoma was more than that in thymoma [72.73% (16 / 22) vs 44.19% (38 / 86), 蠂 ~ 2 5.708 (P ~ (0.017)] .Agna ABB _ 1 type thymoma was round or oval B _ 2 type, and the shape of thymic carcinoma was irregular (蠂 ~ 222.917 P ~ 0.001). There were 6 cases of thymoma and 10 cases of necrotic cysts of thymic carcinoma type B3, respectively. It was significantly higher than other thymomas [51.61% (16 / 31) vs 24.68% (19 / 77)]. The degree of enhancement of thymic carcinoma was mainly moderate enhancement compared with B1OB2OB3 type [58.18% (32 / 55) vs 30.19% (16 / 53) 蠂 ~ 2 11.820 P0. 001]. The imaging staging of thymic carcinoma was stage 鈪，
