背景和目的：Zuckerkandl结节位于甲状腺叶的后内侧边缘，它可能与肿瘤或其他肿块混淆。本研究进行了澄清的位置和形态特征的Zuckerkandl结节解剖尸体，并与相应的CT图像中获得相同cadversis.MATERIALS和METHODS：100甲状腺叶50例新鲜尸体解剖本研究（20男，30女，平均死亡年龄，77.3 - 11.5岁）的结果进行比较。结果：甲状腺祖克尔坎德尔结节的显示率为83%，其解剖前的CT扫描显示率为100%，解剖前的CT扫描显示率为100%。多位于甲状腺叶的后内侧缘和甲状腺叶的中间两个四分之一（第2和第3）。Zuckerkandl结节按其延伸方向分为3型：后内侧型占64%，后内侧和上级型占13%，后内侧和下级型占6%。在轴位CT上，Zuckerkandl结节通常与甲状腺叶的后内侧部分连续，并向后内侧延伸至食管。Zuckerkandl结节的部分突出后内侧和上方或后内侧和上方的甲状腺叶出现分离的甲状腺轴向CT.CONCLUSIONS：Zuckerkandl结节的后内侧和上级或下方的方向突出，可能会造成混乱，由于他们的分离时，执行CT图像诊断。
BACKGROUND AND PURPOSE: The Zuckerkandl tubercle is located at the posteromedial border of the thyroid lobe, and it may be confused with a neoplasm or other mass. This study was performed to clarify the position and morphologic characteristics of the Zuckerkandl tubercle by dissecting cadavers and to compare the findings with the corresponding CT images obtained in the same cadavers.MATERIALS AND METHODS: One hundred thyroid lobes from 50 fresh cadavers were dissected for this study (20 males and 30 females; mean age at death, 77.3 11.5 years). CT scans were obtained in 10 of the cadavers by using a 128-channel multidetector row CT scanner before dissection.RESULTS: The Zuckerkandl tubercle of the thyroid gland was observed in 83% of the specimens. It was mostly located at the posteromedial border of the thyroid lobe and within the middle two quarters (2nd and 3rd) of the thyroid lobe. The Zuckerkandl tubercle was classified into 3 types based on its direction of extension: posteromedial in 64% of the specimens, posteromedial and superior in 13%, and posteromedial and inferior in 6%. On axial CT, the Zuckerkandl tubercle was usually continuous with the posteromedial part of the thyroid lobe and extended posteromedially to the esophagus. The parts of the Zuckerkandl tubercle that protrude posteromedially and superiorly or posteromedially and inferiorly from the thyroid lobe appeared separated from the thyroid gland by a thin, low-density string on axial CT.CONCLUSIONS: Zuckerkandl tubercles that protrude toward the posteromedial and superior or inferior direction could cause confusion due to their separation when performing diagnoses with CT images.
