Morphological variations of the thyroid gland are common and generally occur superior to the gland, reflecting its developmental origin. In this report we describe an accessory lobe located inferior to both lateral lobes and the isthmus. The accessory lobe was supplied by a branch of the right inferior thyroid artery and its vein drained via the plexus thyroideus impar. A discussion of thyroid anomalies is presented and a system for classifying variations of thyroid anatomy is proposed.
甲状腺的形态变异很常见,通常发生在甲状腺上方,这反映了其发育起源。在本报告中,我们描述了一个位于两侧叶和峡部下方的副叶。该副叶由右甲状腺下动脉的一个分支供血,其静脉通过甲状腺奇静脉丛引流。本文对甲状腺异常进行了讨论,并提出了一种甲状腺解剖变异的分类系统。
