An indoor 9-year-old castrated male domestic cat was referred with a 4 month history of increased upper airway noise. Computed tomography revealed a nasopharyngeal polypoid mass, which was removed endoscopically with basket forceps. Histopathology was compatible with a polypoid granulomatous pharyngitis with -like organisms. This was supported by a positive serum latex cryptococcal antigen agglutination test (LCAT). Minimal inflammation of the nasal tissue was noted on histopathology, with no evidence of fungus. Following endoscopic removal of the mass, the patient was treated with systemic antifungal medication (itraconazole). One year after diagnosis, the LCAT titer was negative and the cat remained free of clinical signs.
This case report emphasizes the importance of considering species as a potential etiology in cats presented with signs of nasopharyngeal obstruction with an isolated nasopharyngeal polypoid mass, even if kept indoors.
一只9岁室内阉割雄性家猫因上呼吸道噪音增加4个月的病史前来就诊。计算机断层扫描显示鼻咽部有一个息肉样肿块，用篮式钳经内镜将其切除。组织病理学结果与伴有类似生物体的息肉样肉芽肿性咽炎相符。血清乳胶隐球菌抗原凝集试验（LCAT）呈阳性支持这一诊断。组织病理学检查发现鼻组织仅有轻微炎症，未发现真菌迹象。内镜下切除肿块后，对该猫使用全身性抗真菌药物（伊曲康唑）进行治疗。诊断一年后，LCAT滴度呈阴性，该猫未出现临床症状。
本病例报告强调，对于出现鼻咽部梗阻体征且仅有孤立性鼻咽息肉样肿块的猫，即使是室内饲养的猫，也应考虑将 物种作为潜在病因，这一点很重要。
