一只老年猫的非典型炎性喉咽蹼伴鼻咽狭窄

中文摘要

一只老年去势雄性韩国短毛猫因慢性呼吸窘迫、喘鸣、吞咽困难和严重体重减轻而接受评估。X线摄影和计算机断层扫描显示鼻咽狭窄以及喉咽部一处薄的膜性蹼样阻塞性结构，导致气道近乎完全阻塞，同时额窦和鼓泡内可见液性至软组织衰减物质。手术探查证实为膜性病变，组织病理学显示慢性溃疡性腭炎，无肿瘤证据。本病例提示猫鼻咽狭窄可能与更复杂的炎性喉咽蹼相关，可能拓宽目前对该疾病形态学谱的认识。

英文摘要

An older neutered male Korean Shorthair cat was evaluated for chronic respiratory distress, stertor, dysphagia, and severe weight loss. Radiography and computed tomography revealed nasopharyngeal narrowing and a thin membranous web-like obstructive structure at the laryngopharynx, resulting in near-complete airway obstruction, with concurrent fluid-to-soft tissue attenuating material within the frontal sinus and tympanic bulla. Surgical exploration confirmed a membranous lesion, and histopathology demonstrated chronic ulcerative palatitis without evidence of neoplasia. This case suggests that feline nasopharyngeal stenosis may be associated with a more complex inflammatory laryngopharyngeal web, potentially broadening the currently recognized morphologic spectrum of this condition.
