Hydatid cysts in the thyroid gland are extremely rare, even in endemic areas. A 64-year-old male presented with a painless swelling on the left side of the thyroid swelling for 2 years. Ultrasonography revealed a large multiloculated anechoic lesion while fine needle aspiration cytology yielded clear watery to granular fluid containing hooklets, protoscolioces, laminated membrane, identifiable on both Giemsa stained and unstained slides. Further tests confirmed positive serology for , and computed tomography (CT) scan showed no such cysts in other organs. The patient was treated successfully with a lobectomy without signs of recurrence in 1 year. Although primary hydatid cysts of the thyroid are rare, even in endemic areas, they should be considered as a differential diagnosis when evaluating thyroid nodules in these regions. Fine needle aspiration cytology (FNAC) can confirm the diagnosis. However, clinicians must take care to avoid anaphylactic reactions. The use of FNAC in hydatid disease is debatable as it may cause anaphylactic reaction, but in cases with doubtful diagnosis, it can serve as a confirmatory tool. The condition can be managed successfully with lobectomy.
甲状腺包虫囊肿极为罕见，即使在流行地区也是如此。一名64岁男性因甲状腺左侧无痛性肿胀就诊，病程2年。超声检查显示一个大的多房性无回声病变，细针穿刺细胞学检查抽出清亮水样至颗粒状液体，其中含有小钩、原头节、板层膜，在吉姆萨染色和未染色的玻片上均可识别。进一步检查证实血清学阳性，计算机断层扫描（CT）显示其他器官无此类囊肿。患者接受叶切除术治疗成功，1年内无复发迹象。尽管甲状腺原发性包虫囊肿罕见，即使在流行地区也是如此，但在评估这些地区的甲状腺结节时，应将其视为鉴别诊断之一。细针穿刺细胞学检查（FNAC）可确诊。然而，临床医生必须注意避免过敏反应。FNAC在包虫病中的应用存在争议，因为它可能引起过敏反应，但在诊断存疑的病例中，它可作为一种确诊工具。该疾病通过叶切除术可成功治疗。
