胸腺肿瘤及肿瘤样病变的CT诊断相关分析

Correlation Analysis of CT Diagnosis of Thymic Tumors and Tumor-like Lesions

目的探讨胸腺肿瘤及肿瘤样病变的CT诊断相关观察。方法方便选取该院2016年3月—2020年3月收治的胸腺肿瘤及肿瘤样病变患者62例,62例患者均接受CT诊断以及病理诊断,探究CT诊断胸腺肿瘤及肿瘤样病变的临床意义。结果62例患者的临床特征进行对比,其中胸腺癌占比29.04%、胸腺瘤占比30.65%、胸腺淋巴瘤占比16.13%,胸腺类癌占比3.22%、侵袭性胸腺癌占比16.13%、异位胸腺瘤占比3.22%、颈部胸腺囊肿占比1.61%。50例胸腺肿瘤及肿瘤样病变患者的病理分型显示,异位胸腺瘤位于心室前方、左前下纵膈;颈部胸腺囊肿位于颈部至胸廓入口左侧甲状腺下方。50例胸腺肿瘤及肿瘤样病变患者的CT诊断结果显示,其中有18例患者属于胸腺癌、6例胸腺瘤、9例胸腺淋巴瘤,2例胸腺类癌、10例侵袭性胸腺癌、2例异位胸腺瘤、1例颈部胸腺囊肿。仅有1例胸腺淋巴瘤未诊断出,诊断准确率高达98.39%。结论CT诊断胸腺肿瘤及肿瘤样病变,能够清晰的观察到肿瘤周围结构,及时发现胸腺肿瘤及肿瘤样病变,为临床诊断提供可靠的依据,该诊断方法准确率高度接近病理诊断,可作为胸腺肿瘤及肿瘤样病变患者首选的诊断方法。

Objective To investigate the observation of CT diagnosis of thymic tumors and tumor-like lesions.Methods A total of 62 patients with thymic tumors and tumor-like lesions admitted to the hospital from March 2016 to March 2020 were convenient selected.All 62 patients received CT diagnosis and pathological diagnosis to explore the clinical significance of CT in the diagnosis of thymic tumors and tumor-like lesions.Results The clinical characteristics of 62 patients were compared.Among them,thymic cancer accounted for 29.04%,thymoma accounted for 30.65%,thymic lymphoma accounted for 16.13%,thymic carcinoid accounted for 3.22%,and invasive thymic carcinoma accounted for 16.13%.Ectopic thymoma accounted for 3.22%,and cervical thymic cyst accounted for 1.61%.The pathological classification of 50 patients with thymic tumors and tumor-like lesions showed that ectopic thymoma was located in front of the ventricle and the left anterior inferior mediastinum;cervical thymic cyst was located below the thyroid gland on the left side of the entrance to the thorax from the neck.The CT diagnosis results of 50 patients with thymic tumors and tumor-like lesions showed that 18 of them were thymic cancer,6 thymoma,9 thymic lymphoma,2 thymic carcinoid,10 invasive thymic cancer,and 2 Ectopic thymoma,1 case of neck thymic cyst.Only 1 case of thymic lymphoma was not diagnosed,and the diagnostic accuracy rate was as high as 98.39%.Conclusion CT diagnosis of thymic tumors and tumor-like lesions can clearly observe the surrounding structures of the tumor,and timely find thymic tumors and tumor-like lesions,providing a reliable basis for clinical diagnosis.The accuracy of this diagnostic method is highly close to that of pathological diagnosis,and it can be used as a thymic tumor and the preferred diagnostic method for patients with tumor-like lesions.
