This case report describes a 10-year-old spayed female domestic medium-hair cat with chronic upper respiratory signs related to a remnant of the left globe in the orbit after incomplete enucleation, causing a draining tract. A CT scan, complete blood (cell) count, biochemical analysis, rhinoscopy, biopsy, culture, histopathologic analysis, and surgical revision of enucleation were done. Complete blood (cell) count was unremarkable. Biochemical analysis showed mild hyperglycemia at 9.38 mmol/L [referral range (RR): 3.95 to 8.84 mmol/L] and hyperglobulinemia at 56 g/L (RR: 28 to 51 g/L). The CT scan showed a soft-tissue opacity consisting of a cyst in the orbit from the previously enucleated eye with a draining tract and a completed destruction of the nasal turbinates. was cultured from nasal biopsies. Histopathologic analysis of the nasal tissue showed lymphocytic and neutrophilic rhinitis with edema. Revision surgery was carried out to remove the orbital cysts. Histopathologic analysis of the cyst in the left orbit revealed a distorted globe with almost all the ocular structures. Upon recheck a few weeks later, no discharge from the surgical site was observed. However, mild chronic discharge remained present in both nostrils. This is the first report of incomplete enucleation in a cat leading to chronic nasal signs. Removing the entire globe with the conjunctiva and lacrimal glands is important to minimize postsurgical complications. Key clinical message: This is the first case report of chronic nasal signs secondary to an incomplete enucleation in a cat. Key factors of the surgery include removal of the entire globe with the lacrimal gland, conjunctiva, and eyelid margin to prevent secondary complications.
本病例报告描述了一只10岁已绝育的雌性家养中毛猫，因左眼眼球在不完全摘除术后眼眶内残留，导致慢性上呼吸道症状并形成引流道。进行了CT扫描、全血细胞计数、生化分析、鼻镜检查、活检、培养、组织病理学分析以及眼球摘除术的翻修手术。全血细胞计数无异常。生化分析显示轻度高血糖，血糖值为9.38 mmol/L[参考范围（RR）：3.95至8.84 mmol/L]，球蛋白血症，球蛋白水平为56 g/L（RR：28至51 g/L）。CT扫描显示眼眶内有一个软组织密度影，由先前摘除眼球后的囊肿构成，伴有引流道，鼻甲骨完全破坏。从鼻活检组织中培养出[具体细菌名称未给出]。鼻组织的组织病理学分析显示淋巴细胞性和嗜中性粒细胞性鼻炎伴水肿。进行了翻修手术以切除眼眶囊肿。对左眼眶囊肿的组织病理学分析显示眼球变形，几乎所有眼结构均存在。几周后复查时，未观察到手术部位有分泌物。然而，两个鼻孔仍有轻度慢性分泌物。这是首例猫因不完全眼球摘除导致慢性鼻部症状的报告。完整摘除眼球连同结膜和泪腺对于减少术后并发症很重要。关键临床信息：这是首例猫因不完全眼球摘除继发慢性鼻部症状的病例报告。手术的关键因素包括完整摘除眼球连同泪腺、结膜和眼睑边缘，以预防继发并发症。
