Abstract

Feline nasopharyngeal polyps are benign, pedunculated, inflammatory lesions typically originating from the mucosa of the nasopharynx, auditory tube, or tympanic bulla. These polyps predominantly affect cats younger than three years of age and present with upper respiratory and vestibular symptoms. This case report describes a 15-month-old male domestic shorthair cat suffering from progressive respiratory distress, stridor, and dyspnea. Radiographic imaging revealed a soft tissue mass posterior to the soft palate, in the nasopharyngeal region. Following a thorough diagnostic evaluation, surgical removal of the polyp was performed. Histopathological examination of the excised mass revealed a suppurative granuloma composed primarily of neutrophilic infiltration and fibrous stroma. The patient, after a year's follow-up, had no signs and no clinical sign of recurrence. The present case emphasizes the importance of accurate diagnosis, the value of complete surgical excision, and long-term monitoring to detect potential recurrence. Surgical management is the choice treatment for nasopharyngeal polyps, and outcomes are generally favorable when performed with appropriate technique and follow-up care.
