Abstract Objective To analyze the characteristic of thyroid lesion in 99mTcO4- thyroid scintigraphy and computed tomography(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 pathology and the clinical features.Results In the 19 confirmed thyroid mass by surgery, there are 8 cases of adenoma, 5 cases of adenocarcinoma, 3 cases of nodular goiter, 2 cases of thyroid abscess and 1 case of hamartoma next to thyroid. There are 9 cases of ectopic 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 ectopic lobe. There are also 8 normal cases in CT and 99mTcO4- thyroid scintigraphy. There is 1 case of thyromegaly in the CT and with increased uptake in 99mTcO4- thyroid scintigraphy. The degree of uptake 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.
