Upper airway obstruction in a llama caused by aberrant nasopharyngeal bots (Cephenemyia sp.)

Vet Radiol Ultrasound. 1997 Sep-Oct;38(5):384-6. doi: 10.1111/j.1740-8261.1997.tb02103.x.

Abstract

A 9 month old female llama was presented with inspiratory dyspnea. Radiographically, there was a large soft tissue mass nearly occluding the nasopharynx. During endoscopic examination three nasopharyngeal bots were identified embedded in the mass. The larvae were removed and the patient treated with ivermectin. The patient was discharged one week later free of clinical respiratory disease. In follow-up radiographs made 6 weeks later, only residual radiopacity in the area of the mass remained.
