结节性甲状腺肿的CT表现及分析

An Analysis of CT Diagnosis of Nodular Goiter

[目的]总结结节性甲状腺肿(NG)CT表现,以提高术前诊断正确率。[方法]回顾性分析经手术病理证实546例NG的CT表现。[结果]单结节型(151/546),多结节型(352/546),弥漫型(43/546)。全部病灶边界清晰,包膜完整,多数伴有囊变,占73%(398/546)。[结论]病灶多发、包膜完整、伴有明显囊变是NG较有特异性的CT表现。

Purpose] To investigate CT imaging of the Nodular goiter (NG) to improve diagnostic accuracy preoperation. [Methods] The CT imaging in 546 cases with NG histopathologically proved was studied retrospectively. [Results] The CT findings of NG could be classified into mononodular type (151/546), multinodular type (352/546) and diffuse type (43/546). Well-defined margin and full capsula were found in all NG lesion. Cystoid change occurred in 398 cases. [Conclusion] The multiple, full capsula and cystoid change lesion in Thyroid could be considered specific CT features of Nodular goiter.
