Abstract

An 8-year-old, neutered male Yorkshire Terrier dog presented with left ventromedial canthus swelling over a one-month period, refractory to pharmacological therapy. There was no history of trauma. On ultrasonography, the lesion had a cystic character filled with anechoic fluid and hyperechoic sedimenting debris. The computed tomography (CT) and CT-dacryocystography showed a cystic lesion protruding from the lacrimal sac fossa and occupying a defect in the orbital plate and an ethmoidal ectoturbinate surrounded by a bony structure with an intact nasolacrimal system. The dog underwent the surgical resection of the cyst and its fluid content was aspirated. Ethmoid mucocele was diagnosed based on the CT, cytologic examination, bacterial culture and histopathologic findings. This case describes the imaging characteristics of an ethmoid mucocele and highlights the importance of CT and CT-dacryocystography in dogs with ventromedial canthus swelling that had poor response to medical treatment.

约克夏犬鼻窦黏液囊肿的影像学诊断
一个8岁,绝育的雄性约克夏犬左腹内眦肿胀超过一个月的时间,难以药物治疗。没有外伤史。在超声检查上,病变呈囊性特征,充满无回声液体和高回声沉积碎屑。计算机断层扫描(CT)和CT-泪囊造影术显示一囊性病变从泪囊窝突出,占据眶板和筛状外鼻甲的缺损,被完整鼻泪系统的骨结构包围。这只狗接受了手术切除囊肿并抽吸其液体内容物。根据CT、细胞学检查、细菌培养和组织病理学检查诊断为筛黏液囊肿。本病例描述了筛样黏液囊肿的影像学特征,并强调了CT和CT-泪囊造影术对治疗反应不佳的腹内眦肿胀犬的重要性。
