儿童甲状腺病变的核素显像及CT表现

The Characteristic of Thyroid Lesion Present in ^(99)mTcO_4^- Thyroid Scintigraphy and Compute Tomography

目的分析儿童甲状腺病变的核医学^(99)mTcO_4^-甲状腺显像及CT的表现特征,结合临床及术后病理,总结甲状腺的病变及CT表现,并探讨其诊断价值。方法搜集本院2009年12月-2016年5月48例儿童甲状腺病变(男14例,女34例,中位年龄11.5岁),且行^(99)mTcO_4^-甲状腺显像和/或CT检查患者的病例资料,其中19例甲状腺肿块病例均经手术证实,余29例结合临床及实验室检查诊断。将影像诊断(^(99)mTcO_4^-甲状腺显像、CT)与术后病理结果及临床诊断进行对照分析。结果 19例甲状腺肿块中包括腺瘤8例、腺癌5例、结节性甲状腺肿3例、甲状腺脓肿2例、腺旁错构瘤1例。9例异位甲状腺中1例为舌骨水平上下3个结节状改变、1例为舌根及颈前双重异位、余5例位于舌根部(2例为舌根区单个异位改变)。8例正常位置未见明显放射性摄取,1例可见增大的甲状腺,且摄取明显增多。甲状腺炎症根据病程变化有不同程度的摄取增加或减少。结论^(99)mTcO_4^-甲状腺显像及CT在诊断甲状腺病变中有重要辅助作用。

Abstract： Objective To analyze the characteristic of thyroid lesion in ^99mTcO4^- thyroid scintigraphy and computed tomo- graphy （CT） and evaluate the diagnosis value of the two imaging methods. Methods 48 patients with thyroid lesion （male 14, female 34） are included in this retrospective study from December 2009 to May 2016, the median age is 11.5 years old. These cases underwent ^99mTcO4^- thyroid scintigraphy and/or CT scan and the clinical data are collected. 19 cases were diagnosed as mass by ^99mTcO4^- thyroid scintigraphy and CT and confirmed diagnosed by surgery, 29 cases were diagnosed by clinical and laboratory exam. The characteristic of ^99mTcO4^- thyroid scintigraphy and CT is analyzed and compared to the postoperative pa- thology and the clinical features. Results In the 19 confirmed thyroid mass by surgery, there are 8 cases of adenoma, 5 cases of adenoearcinoma, 3 cases of nodular goiter, 2 cases of thyroid abscess and 1 case of hamartoma next to thyroid. There are 9 cases of eetopie thyroid, in which there are 1 case located in the level of lingual duct present three nodule - like change, 1 case located both in the root of tongue and anterior region of neck ,5 cases located in the root of tongue only and 2 cases located in the region of tongue with one individual eetopic lobe. There are also 8 normal cases in CT and ^99mTcO4^- thyroid scintigra- phy. There is 1 case of thyromegaly in the CT and with increased uptake in ^99mTcO4^- thyroid scintigraphy. The degree of up- take in the thyroiditis depends on the process of disease which can be more or less. The ^99mTcO4^- thyroid scintigraphy and CT exam agree well with the the result of surgery and clinical feature. Conclusion ^99mTcO4^- thyroid scintigraphy and CT scan play an important role in the diagnosis of thyroid lesion.
