| 目的 探讨结节性甲状腺肿CT双期增强扫描的表现及鉴别诊断价值。方法 回顾性分析经手术、病理证实的49例结节性甲状腺肿的CT资料。结果 单发20例(40.8%),多发29例(59.2%),多发病例均表现为瘤体大小、密度不一。大部分瘤体CT平扫呈低密度,增强后不同程度强化,仅5例多发病灶其中部分病灶平扫不显示,增强后显示。15例完全囊变,囊壁内外均无强化, 6例出现明显强化类圆形壁结节, 21例不完全囊变病灶实性部分呈类似于肝血瘤样渐进性强化,10例实性病灶显示从中心向外周扩展渐进强化。15例出现低密度环样包膜,增强后包膜渐进性明显强化。结论 结节性甲状腺肿的CT双期增强表现具有一定的特征,对与肿瘤及结节内急性出血鉴别较有价值。 |

| Objective: To study the characteristics and differential value of the two-phase enhanced CT scan mode in nodular goiter. Methods: 49 cases of pathologically confirmed nodular goiter were retrospectively analyzed. Results: Single nodular was found in 20 patients(40.8%), multi-nodular were found in 29 patients(59.2%). Size and density of lesions were different in multi-nodular cases. Most nodular were hypodensity in CT plain scan and various enhanced characteristics in CT contrast scan. Only 5 patients with multi-nodular, no lesions were found in CT plain scan, but some of lesions were showed in enhanced CT scan. Cystoid change in 15 cases, no enhanced characteristics were found in cyst wall. Markedly enhanced wall was found in 6 patients. Partly cystic lesions of 21 cases showed increasingly enhancement as hepatic hemangioma. 10 cases with solid lesion showed increasingly enhanced from center to surrounding of lesion. 15 cases showed hypodensity envelope with obviously increasingly enhanced. Conclusion: Two-phase enhanced CT scan mode provided certain value for differentiation of carcinoma and acute hemorrhage in nodular goiter. |
