Eversion of the laryngeal ventricle is a rare lesion that presents with cough and/or voice changes. Laryngoscopy reveals a polypoid mass arising from the ventricle. Microscopically a polyp covered with ventricular mucosa and containing normal laryngeal mucous glands is seen. Chronic inflammation is usually present.
Treatment in symptomatic cases consists of surgical removal endoscopically or by laryngofissure. The management of one patient is reported with a discussion of the cause, symptoms, and treatment of this condition.
