摘　　要：目的　探讨儿童甲状腺肿瘤的CT表现。资料与方法　对 12例经手术及病理证实的儿童甲状腺肿瘤进行回顾性分析。其中甲状腺腺瘤 9例 ,甲状腺癌 2例 ,淋巴瘤 1例。结果　甲状腺腺瘤中囊实性 4例 ,实性 5例。其中 1例实性甲状腺腺瘤伴桥本甲状腺炎 ,表现为弥漫性甲状腺组织内一稍高密度肿块影 ,增强后明显强化 ;其余8例平扫为低于甲状腺组织的低密度肿块 ,均无钙化 ,增强扫描后呈均匀或不均匀明显强化。甲状腺癌 2例均为弥漫性的肿块 ,增强前后密度极不均匀 ,与周围组织分界不清 ,并伴有颈部淋巴结增大。淋巴瘤 1例 ,为局限性均匀低密度影 ,占位较明显 ,增强后强化明显。结论　CT有助于诊断儿童甲状腺肿瘤 。Objective To investigate CT features of thyroid tumors in children.Materials and Methods Both plain and enhanced CT findings in 12 cases with pathologically-proved thyroid tumor were retrospectively analyzed. The lesions included thyroid adenoma (n=9), carcinoma (n=2) and lymphoma (n=1). Results Of 9 thyroid adenomas, 4 were cyst-solid and 5 were solid. One case was complicated with Hashimoto's thyroadenitis, presenting as a slight-high density shadow within the diffusely enlarged thyroid tissue. The other 8 cases displayed as low-density mass without calcification on plain CT scans and showed homogeneous or heterogeneous enhancement on enhanced CT scans. Two thyroid carcinomas were manifested as ill-defined mass with heterogeneous density. Cervical lymphadenopathy was accompanied in both cases. The lymphoma was characterized by localized low-density shadow with space-occupying effect and enhancement.Conclusion Thyroid tumor in children has certain CT characteristics, which are very helpful for the early diagnosis of the disease.
