目的：探讨原发性甲状腺淋巴瘤的CT表现，以提高对该病的影像诊断水平。方法回顾性分析40例经病理证实的原发性甲状腺淋巴瘤的CT表现。40例中男10例，女30例，年龄37～79岁，中位年龄58岁。对肿瘤的部位、大小、形态、边缘、CT密度及强化形式进行分析。结果40例患者中，单侧32例，双侧8例，2例峡部同时受累，共50个病灶，30例合并慢性淋巴细胞性甲状腺炎；病灶最大径＜5 cm者44个，呈边缘光整、类圆形或椭圆形肿块；＞5 cm者6个，呈边缘不光整、椭圆形或不规则分叶状肿块，其中2个病灶包绕同侧颈总动脉，1个侵犯气管，1个侵犯颈前肌群。CT平扫病灶呈稍低密度36个，等密度14个；密度均匀47个，不均匀3个。增强后病灶轻度强化30个，中度强化16个，明显强化4个。4例伴上纵隔淋巴结肿大，肿大的淋巴结密度均匀，增强扫描呈轻中度强化。结论原发性甲状腺淋巴瘤多表现为甲状腺区塑型生长、密度均匀、轻中度强化的软组织肿块，肿瘤大者易侵犯邻近结构。

Objective To evaluate the CT findings of primary thyroid lymphoma.Methods CT of 40 patients(10 men,30 women,median age 58 years)with pathologically proved primary thyroid lymphomas was reviewed.The location,size,morphology, margin,CT density and enhancement pattern were recorded.Results Of 40 patients with 50 lesions,30 were combined with Hashimoto's disease.The maximum diameter of the lesions ranged from 1.3 to 7.5 cm.The lesions were round(8),oval(38)or irregular(4).Forty-four lesions smaller than 5 cm were round or oval masses with well-defined margins.Six lesions larger than 5cm were oval or irregular masses with unclear margin with invasion of the ipsilateral carotid artery(2),trachea(1)and ipsilateral cervical muscle(1).Compared to normal muscle,36 lesions were slightly hypodense and 14 isodense on unenhanced CT.The lesions were homogeneous(47)or heterogeneous(3)in density with mild(30),moderate(16)or marked(4)contrast enhancement.The superior mediastinal lymphadenopathy in 4 patients was homogeneous in density with mild to moderate contrast enhancement.Conclusion Most of the thyroid lymphomas manifested as soft tissue masses with homogeneous density and slight to moderate enhancement.The larger lesions were more likely to invade the adjacent structure.
