摘要
背景与目的:目前在甲状腺癌的诊治方面,普遍存在术前误诊率高(达40%~70%)和首次术后癌残留率高(达30%)两方面不足。本研究旨在探讨甲状腺癌CT表现与组织病理的相关性,提高其诊断准确率。方法:回顾性分析46例甲状腺癌患者的术前CT及术后病理结果。结果:46例甲状腺癌中31例密度不均匀,30例形态呈不规则状,37例肿瘤边缘模糊不清楚,16例出现瘤周“半岛状”瘤结节,10例瘤周“强化残圈”征;20例肿瘤出现钙化(其中9例细沙粒状钙化,7例混合性钙化,7例表现“囊内钙化性结节”);23例肿瘤侵犯周围组织器官,15例出现颈部淋巴结转移。结论:甲状腺癌的CT表现具有一定特征性,不同病理类型与钙化形式、外周受侵情况关系密切,在一般情况下可以作出正确的术前诊断,并为临床治疗方法的选择提供依据。
BACKGROUND & OBJECTIVE:In clinical diagnosis and treatment of thyroid carcinoma, the misdiagnosis rate is about 40%-70% and the recurrence is about 30%. This study was designed to investigate the relationship between the CT features of thyroid carcinoma and its clinical pathology. METHODS:Fourty six cases of thyroid carcinoma,pathologyically proven,were retrospectively analyzed for CT and histological findings. RESULTS:Of 46 patients with thyroid carcinoma, 31 cases showed heterogeneous density, 30 cases showed irregular shape,37 cases showed untidy margin,16 cases showed peninsluar tubercles around the tumor,and 10 cases showed no complete enhanced ring around the tumor. 20 cases were detected calcifications,including 9 cases fine globular calcifications, 4 cases nodular calcifications, 7 cases mixture calcifications. In addition,“calcified nodule in cyst sign” were found in 7 cases. 23 cases infiltrated the adjacent structures and 15 cases were revealed metastatic lymphadenopathy on the neck. CONCLUSION:Some cases of thyroid carcinoma can be diagnosed correctly according to the characteristic manifestations on CT. Different pathological types of thyroid carcinoma were related to calcification manifestations and adjacent structure invasion. CT scan can provide reliable information in selecting therapeutic methods.
