【摘要】：目的观察不同组织学分型胸腺上皮性肿瘤(TET)的MSCT表现特征。方法回顾性分析108例经手术或穿刺病理证实TET的术前CT表现,并与2004年WHO分型标准比较,探讨不同组织类型TET的CT特征。结果 108例中,A型胸腺瘤3例,AB型30例,B1、B2、B3型分别为15例、29例、9例,胸腺癌22例。合并重症肌无力(MG)者32例(32/108,29.63%)。合并MG患者中,B型胸腺瘤者明显高于其他分型[45.28%(24/53)vs 14.55%(8/55),χ2=12.23,P0.001]。胸腺癌最大径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型胸腺瘤多呈圆形或卵圆形,B2型多呈分叶状,胸腺癌形态多不规则(χ2=32.917,P0.001)。B3型胸腺瘤和胸腺癌坏死囊变发生例数分别为6例和10例,明显高于其他胸腺瘤[51.61%(16/31)vs 24.68%(19/77),2χ=7.322,P=0.007]。与B1、B2、B3型相比,A、AB型、胸腺癌强化程度以中度强化为主[58.18%(32/55)vs 30.19%(16/53),2χ=11.820,P=0.001]。胸腺癌影像分期多为Ⅲ期,与其他型分布比较差异有统计学意义[54.55%(12/22)vs 13.95%(12/86),2χ=38.958,P0.001]。影像分期与临床分期有相关性(r=0.548,P0.01)。结论不同组织类型TET的CT表现具有一定特征性。CT可在一定程度预测TET组织学类型,提示临床分期及预后。
[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，
