摘要
目的:分析原发性甲状腺淋巴瘤(PTL)超声和CT影像学表现。方法:回顾性分析病理诊断为PTL的39例超声和21例CT影像学表现。结果:患者平均年龄65岁。超声表现:弥漫型PTL 10例,其中8例甲状腺肿大,9例腺体回声不均匀性减低,8例腺体后方回声增强,2例腺体内出现钙化;结节型PTL 29例,其中19例出现甲状腺回声不均匀性减低和腺体后方回声增强,26例结节回声减低,3例结节内出现钙化;39例PTL中26例颈部淋巴结肿大;CT表现:弥漫型PTL 4例,2例病灶呈低密度,1例病灶内出现钙化;结节型17例,14例病灶呈低密度,2例病灶出现钙化,以上21例PTL的CT在分型与超声分型呈现对应关系,8例颈部淋巴结肿大,4例上纵隔淋巴结肿大。在14例增强CT中10例为轻中度强化,9例为均匀强化。结论:PTL超声与CT表现各自具有特征性,两者可相互补充,有助于PTL的诊断。
Objective: To evaluate imaging findings with ultrasound and CT imaging techniques in primary thyroid lymphoma(PTL). Methods: 39 cases of histopathologically proven PTL were gathered for this study. We retrospectively reviewed the sonographic and CT findings of PTL. Results: The mean age of the patients was 65 years old. In sonography, there were10 cases of diffuse PTL, of which 8 showed enlargement of the thyroid gland and enhancement of post acoustic, 9 showed hypoechogenicity, and 2 showed calcification in lesions;The cases of nodular PTL were 29, of which 19 showed hypoechogenecity and post acoustic enhancement of thyroid, 26 showed reduced echo of lesions, and 3 showed calcification in lesions.26 of 39 PTL patients had cervical lymph node enlargement. In axial plain CT scans, there were 4 cases of diffuse PTL, 2 cases showed low density, and 1 case showed calcification in lesions;The cases of nodular PTL were 17, 14 cases showed low density, and 2 cases showed calcification in lesion. The above 21 cases showed the same classification types in sonographic and CT findings, of which 8 cases showed cervical lymphadenopathy and 4 cases showed upper mediastinal lymphadenopathy. Of the 14 patients who underwent contrast-enhanced axial CT images, 10 were moderately or mildly enhanced and 9 were homogeneous enhanced. Conclusion: The ultrasonography and CT findings of patients with PTL have corresponding imaging characteristics, and these two can be complementary which help to diagnose PTL.
