摘　　要：目的探讨甲状腺单发囊性病变的CT表现和鉴别诊断要点。方法回顾性分析经病理或临床证实的甲状腺单发囊性病变48例的CT表现。结果甲状腺单发囊性病变可分为3类:(1)单纯囊肿型(35例);(2)囊壁结节型(4例);(3)厚壁肿块型(9例)。其中,25例甲状腺瘤周围出现光滑整齐的明显强化环,2例甲状腺癌周围出现残缺不全的明显强化环,2例甲状腺脓肿周围可见“双环”状强化。单纯囊肿型常见于良性病变(35/35),而厚壁肿块型常见于恶性病变(7/9)(P<0.01)。结论(1)周围光滑整齐的强化环是甲状腺瘤的特征性表现;(2)“双环征”是甲状腺脓肿的特征性表现;(3)单纯囊性型常见于良性病变,而厚壁肿块型常见于甲状腺癌。Objective To study the CT findings and differential diagnosis of solitary thyroid cystic lesions. Methods 48 cases of solitary thyroid cystic lesions confirmed pathologically were analysed retrospectively. Results According to the CT findings,the lesions could be divided into there types ： type Ⅰ simple cyst （ n = 35 ） , type Ⅱ cyst with nodule on the wall （ n = 4 ） and type Ⅲ cyst with thick wall and/or round mass on it （ n = 9 ）. The enhanced ring appeared in thyroid adenomas was complete （ n = 25 ） in comparison with the enhanced ring was fragmentary appeared in thyroid carcinoma （n = 2 ） , double circle enhanced ring appeared in abscess （n = 2 ）. Type Ⅰ more common appeared in benign lesions （ 35/35 ） in comparison with typeⅡin malignant lesions （ 7/9 ） （ P 〈 0.01 ）. Conclusion （ 1 ） The complete enhanced ring on CT scan is the characteristic of thyroid adenomas ; （ 2 ） Double circle enhanced is the characteristic of thyroid abscess ; （ 3 ） Type Ⅰ is common seen in benign lesions,while type Ⅲ is common seen in thyroid carcinoma.
