Hemiagenesis of the thyroid gland is a rare congenital abnormality usually left unnoticed without associated thyroid disorders. The most common congenital anomaly of the thyroid gland is a thyroglossal cyst, followed by ectopic thyroid tissue and thyroid dysgenesis, which may be agenesis or hemiagenesis. Preoperative underevaluation of the thyroid hemiagenesis (THA) associated with other thyroid disorders may cause intraoperative difficulty in identifying the gland and difficulty in preservation or even identification of major neurovascular structures during neck exploration. We report a patient who presented to us with right-sided neck swelling. On further evaluation and neck exploration, the patient was diagnosed with THA of the left lobe with right colloid goitre.
甲状腺半侧发育不全是一种罕见的先天性异常，通常无相关甲状腺疾病而不被察觉。甲状腺最常见的先天性异常是甲状舌管囊肿，其次是异位甲状腺组织和甲状腺发育不良，可能是发育不全或半侧发育不全。术前对伴发其他甲状腺疾病的甲状腺半侧发育不全（THA）评估不足，可能导致术中识别该腺体困难，在颈部探查过程中难以保留甚至识别主要的神经血管结构。我们报告了 1 例以右侧颈部肿胀就诊的患者。进一步评估和颈部探查后，患者被诊断为左侧甲状腺半叶发育不全合并右侧胶质性甲状腺肿。
