Abstract:
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.
