A 7-year-old neutered male alpaca (Vicugna pacos) was presented for evaluation of a 3-year history of large, bilateral, firm ventral cervical masses causing esophageal and tracheal impingement. Ultrasound examination, radiographic evaluation, histopathological findings, and magnetic resonance imaging confirmed the masses to be bilateral thyroid adenomas. Conservative medical treatment by unilateral chemical ablation, using 10% formalin by aspiration technique, was performed on the left mass. Chemical ablation proved to be effective in decreasing the size of the mass, with no apparent adverse effects. To our knowledge, this case is the first known report of bilateral thyroid adenomas in an alpaca, a condition previously described in humans, horses, dogs, and cats.
一只 7 岁去势雄性羊驼（Vicugna pacos）因 3 年双侧大而坚实的颈前肿块导致食管和气管受压而就诊。超声检查、影像学评估、组织病理学发现和磁共振成像证实肿块为双侧甲状腺腺瘤。通过抽吸技术用 10%福尔马林对左侧肿块进行单侧化学消融的保守治疗。化学消融被证明能有效减小肿块的大小，且无明显不良反应。据我们所知，这是首例已知的羊驼双侧甲状腺腺瘤病例，这种情况以前仅在人类、马、狗和猫中描述过。
