An eight-year-old domestic shorthair cat was evaluated because of dyspnoea secondary to pleural effusion. Ultrasound examination identified a large anechoic cyst-like structure in the caudal thorax. A median sternotomy was performed, and the cystic mass was removed. Microscopically, the excised tissue was identified as a multilocular thyroglossal duct cyst with ectopic thyroid tissue. To the authors' knowledge, this is the first report of a mediastinal thyroglossal duct cyst in a cat. Despite the rarity of this lesion, it should be considered when a cystic thoracic structure is identified on thoracic ultrasound. Surgical excision of the cyst resulted in complete resolution of the pleural effusion and clinical signs.
一只八岁的家养短毛猫因胸腔积液继发呼吸困难而接受评估。超声检查发现尾侧胸腔有一个大的无回声囊肿样结构。进行了正中胸骨切开术，并切除了囊性肿物。显微镜下，切除的组织被鉴定为含有异位甲状腺组织的多房性甲状舌管囊肿。据作者所知，这是猫纵隔甲状舌管囊肿的首例报告。尽管这种病变罕见，但当胸部超声发现囊性胸部结构时应予以考虑。囊肿的手术切除导致胸腔积液和临床症状完全缓解。
