Nasal hamartoma causing stenosis and partial obstruction in a Siamese cat

A 6-year-old, female neutered, Siamese cat was presented to the referral centre due to a mass causing obstruction of the left nostril that was previously diagnosed histologically as a nasal hamartoma. The mass was causing significant respiratory compromise to the cat resulting in open-mouth breathing at rest. A computed tomography (CT) scan demonstrated a 48% mediolateral narrowing of the left nostril compared with the right nostril in a mediolateral direction. Surgical excision of the mass re-established the left lateral alar groove and increased the nostril luminal width by 45% when compared with preoperative measurements. Two years after surgery, there was no recurrence of the mass and the cat had sustained significant improvement to their respiratory function and quality of life.
