超声联合CT诊断原发性甲状腺淋巴瘤的价值观察

Value of Ultrasound Combined with CT in Diagnosising Primary Thyroid Lymphoma

目的探究原发性甲状腺淋巴瘤诊断联合超声与CT诊断价值。方法回顾性分析2015年5月至2019年5月我院收治的34例疑似原发性甲状腺淋巴瘤患者相关资料,所有患者均接受超声与CT检查。分析病理结果,进行超声与CT诊断原发性甲状腺淋巴瘤符合率比较,分析原发性甲状腺淋巴瘤超声与CT表现以及两者联合诊断价值。结果所有患者通过病理检查以及病灶免疫组化染色证实有32例患者为原发性甲状腺淋巴瘤,淋巴瘤类型均为B细胞型非霍奇金淋巴瘤;超声与CT诊断原发性甲状腺淋巴瘤诊断符合率分别为87.50%(28/32)和93.75%(30/32),超声与CT联合诊断符合率为100.00%(32/32),三种诊断方式诊断符合率差异无统计学意义(χ^(2)=4.273,P>0.05);超声检查显示病灶尺寸为(52.83±3.57)mm,以双侧病变为主(18例/64.29%),弥漫型与非弥漫型17例(60.71%)和11例(38.26%),多显示为粗糙不匀低回声,彩色多普勒超声发现患者病灶内部血流主要为1级与2级,病灶形态多为不规则状,且界线不清;CT扫描发现病灶尺寸为(50.54±2.69)mm,主要以双侧病变为主(18例/60.00%),结节型、多发结节型、弥漫型病变分别有5例(16.67%)、6例(20.00%)、19例(63.33%);平扫时多显示为中低密度回声;14例(46.67%)患者可以明显观察到病灶累及周围组织,12例(53.33%)患者病灶累及血管;超声与CT超声联合诊原发性甲状腺淋巴瘤灵敏度、特异度与准确度均为100%,联合诊断灵敏度、特异度与准确度均高于单一诊断。结论超声与CT用于诊断原发性甲状腺淋巴瘤能够有效提高其诊断水平,但是两者联用诊断价值更高。

Objective To explore diagnostic value of ultrasound combined with CT in primary thyroid lymphoma(PTL).Methods A retrospective analysis was performed on related data of 34 patients suspected with PTL admitted to the hospital from May 2015 to May 2019.All patients underwent ultrasound and CT examination.The pathological results,diagnostic coincidence rates of ultrasound,and CT for PTL were analyzed.The ultrasound and CT findings of PTL were analyzed.Results Among all patients confirmed by pathological examination and immunohistochemical staining,there were 32 cases with PTL,and lymphoma type was B-cell non-Hodgkin's lymphoma.The diagnostic coincidence rates of ultrasound and CT for PTL were 87.50%(28/32)and 93.75%(30/32),respectively.The diagnostic coincidence rate of their combination was 100.00%(32/32).There was no significant difference in diagnostic coincidence rate among the three diagnostic methods(χ^(2)=4.273,P>0.05).The ultrasound examination showed lesion size was(52.83±3.57)mm,mainly on bilateral lesions[(18 cases/64.29%)],diffuse and non-diffuse type[17 cases(60.71%),11 cases(38.26%)],mostly showing rough and uneven hypoecho.The color Doppler ultrasound found that blood flow inside lesions was mainly on grade 1 and grade 2.The lesion morphology was mostly irregular,and the boundary was unclear.CT scan found that lesion size was be(50.54±2.69)mm,mainly on bilateral lesions[(18 cases/60.00%)].There were 5 cases(16.67%),6 cases(20.00%),and 19 cases(63.33%)with nodule,multi-nodule and diffuse lesions.The plain scan mostly showed medium to low density echo.There were 14 cases(46.67%)with lesions involving in surrounding tissues,and 12 cases(53.33%)involving in vessels.The sensitivity,specificity,and accuracy of ultrasound and CT combined with ultrasound in diagnosis of PTL were all 100%.The sensitivity,specificity,and accuracy of combination diagnosis are higher than those of single diagnosis.Conclusion Ultrasound and CT can effectively improve diagnosis level for PTL.However,diagnostic value of their combination is higher.
