目的 分析胸腺疾病的多层螺旋CT(MSCT)图像表现,探寻鉴别不同胸腺疾病的征象.方法 回顾性分析经手术及病理证实的39例胸腺病变的MSCT表现,根据病理结果将其分为三组,即良性及低危组、高危组、癌及类癌组,观察内容包括每组病变的位置、最长径(测两次取平均值)、形态、边缘、密度、周围侵犯和转移情况、强化程度等,比较各组间上述征象差别.结果 39例胸腺病变中良性及低危组21例,高危组13例,癌及类癌组5例,三组之间在病灶的形态、边缘、密度、周围侵犯情况上差异有统计学意义(P＜0.05),其中在不规则形态、不均匀密度方面癌及类癌组与良性及低危组分别为5,4例与1,3例,两组比较差异有统计学意义(P＜0.05);在周围侵犯情况上,高危组与癌及类癌组之间差异无统计学意义(P＞0.05),但二者与良性及低危组间差异均有统计学意义(P＜0.05).在病变的长径和强化程度方面三组之间差异均无统计学意义(P＞0.05).结论 MSCT对各种胸腺疾病的鉴别诊断具有重要价值.
目的 分析胸腺疾病的多層螺鏇CT(MSCT)圖像錶現,探尋鑒彆不同胸腺疾病的徵象.方法 迴顧性分析經手術及病理證實的39例胸腺病變的MSCT錶現,根據病理結果將其分為三組,即良性及低危組、高危組、癌及類癌組,觀察內容包括每組病變的位置、最長徑(測兩次取平均值)、形態、邊緣、密度、週圍侵犯和轉移情況、彊化程度等,比較各組間上述徵象差彆.結果 39例胸腺病變中良性及低危組21例,高危組13例,癌及類癌組5例,三組之間在病竈的形態、邊緣、密度、週圍侵犯情況上差異有統計學意義(P＜0.05),其中在不規則形態、不均勻密度方麵癌及類癌組與良性及低危組分彆為5,4例與1,3例,兩組比較差異有統計學意義(P＜0.05);在週圍侵犯情況上,高危組與癌及類癌組之間差異無統計學意義(P＞0.05),但二者與良性及低危組間差異均有統計學意義(P＜0.05).在病變的長徑和彊化程度方麵三組之間差異均無統計學意義(P＞0.05).結論 MSCT對各種胸腺疾病的鑒彆診斷具有重要價值.

Objective To analyze the multislice CT (MSCT) imaging performance of various kinds of thymic lesions and to explore useful signs for differentiating those lesions.Methods CT features of 39 cases with thymic lesions confirmed by operation and pathology were reviewed retrospectively analyzed and these cases were divided into three groups,namely low-risk group,high-risk group,cancer and carcinoid group.The imaging characteristics of each group including location,size,shape,border,density,invasion and metastasis,degree of enhancement were compared and the main different characteristics among the three groups were analyzed.Results Among the 39 cases,21 were low-risk,13 were high-risk and 5 were cancer and carcinoid.There were significant difference among the three groups in shape,border,density,invasion and metastasis of these thymic lesions on CT imaging (P ＜ 0.05).As for the irregular shape and nonuniform density,there were 5 and 4 cases in cancer and carcinoid group and only 1 and 3 cases in low-risk group,the difference between the two groups were statistically significant(P ＜ 0.05).As for invasion and metastasis,there were no statistical significant between the high-risk group and the cancer and carcinoid group,but both had statistical significant with the low-risk group respectively (P ＜ 0.05).No significant difference existed among the three groups in size and degree of enhancement(P ＞ 0.05).Conclusion MSCT might be an effective and important imaging tool for differentiating various kinds of thymic lesions.
