CASE SUMMARY
A 14-year-old neutered female Burmese cat was referred for investigation of a caudal oropharyngeal mass. CT showed a thin walled cyst-like structure filling and expanding from the right tympanic bulla. Histopathology showed fragments of mildly dysplastic squamous epithelium and aggregates of keratin. These findings were considered consistent with a diagnosis of cholesteatoma.
RELEVANCE AND NOVEL INFORMATION
To the best of our knowledge, this is the first reported case of a cholesteatoma in a cat. Cholesteatoma should be considered a differential diagnosis for cats presenting with a caudal oropharyngeal mass, a history of chronic ear disease or a history of previous, surgically managed middle ear disease. Advanced imaging and biopsies should be considered important in the diagnosis of these lesions.
病例摘要
一只14岁已绝育的缅甸母猫因尾侧口咽部肿物接受检查。CT显示一个薄壁囊肿样结构，从右鼓室填充并扩张。组织病理学显示轻度发育异常的鳞状上皮碎片和角蛋白聚集体。这些发现被认为与胆脂瘤的诊断一致。
相关性及新信息
据我们所知，这是首例猫胆脂瘤的报道病例。对于出现尾侧口咽部肿物、有慢性耳部疾病史或既往有中耳手术治疗史的猫，应将胆脂瘤视为鉴别诊断之一。在这些病变的诊断中，先进的影像学检查和活检应被视为重要手段。
