Intratracheal ectopic thyroid tissue is an extremely rare condition with limited cases reported in the literature. It can be asymptomatic or present with symptoms such as dysphagia, bleeding, dysphonia, dyspnea, and a sensation of a foreign body in the throat, depending on its localization. Due to its various clinical presentations, it poses a diagnostic dilemma. Herein, we aimed to present the contribution of thyroid scintigraphy and SPECT/CT to the diagnosis and management of a case with follicular carcinoma in the orthotopic thyroid gland as well as an ectopic intratracheal thyroid causing cough and airway obstruction mimicking a subglottic mass.
气管内异位甲状腺组织是一种极为罕见的病症，文献报道的病例有限。根据其位置不同，它可能无症状，或表现为吞咽困难、出血、声音嘶哑、呼吸困难以及咽喉部异物感等症状。由于其临床表现多样，给诊断带来了难题。在此，我们旨在介绍甲状腺闪烁显像和SPECT/CT对一例原位甲状腺滤泡癌以及一例引起咳嗽和气道梗阻、酷似声门下肿物的气管内异位甲状腺病例的诊断和管理所起的作用。
