Abstract

One hundred consecutive thyroid images obtained by use of Tc-99m pertechnetate, in authenticated cases of hyperthyroidism, were reviewed. Calibrated images showed that only 42 of the 200 thyroid lobes (21%) were greater than 5 cm in length. The enlarged lobes occurred in 29 patients. Of these, only 4 had a multinodular appearance (and 7 patients with smaller lobes also had multinodular glands). Neither thyromegaly (by length) nor multinodular appearance are common features of hyperthyroidism in this area. There were 12 instances of pyramidal lobes in the hyperthyroid men (12 of 26 = 46%) and 24 cases in women (24 of 74 = 32%). The site of origin of the pyramidal lobe was from the left in 17, from right in 16, and from the midline in 3 cases. During the period of review of all thyroid images, only one other case of a pyramidal lobe was found (a case of multinodular goiter).

摘要

回顾了连续100例经证实的甲状腺功能亢进病例中使用锝-99m高锝酸盐获得的甲状腺图像。校准后的图像显示，200个甲状腺叶中只有42个（21%）长度大于5厘米。肿大的叶出现在29例患者中。其中，只有4例呈多结节外观（7例叶较小的患者也有多结节腺体）。在该地区，甲状腺肿大（按长度）和多结节外观均不是甲状腺功能亢进的常见特征。甲状腺功能亢进男性中有12例出现锥状叶（26例中的12例 = 46%），女性中有24例（74例中的24例 = 32%）。锥状叶的起源部位，17例来自左侧，16例来自右侧，3例来自中线。在所有甲状腺图像回顾期间，仅发现另外1例锥状叶病例（1例多结节性甲状腺肿）。
