[Pyolaryngocele: case report of an uncommon laryngeal disease]

Laryngocele is an unusual laryngeal disease caused by an abnormal dilatation of the saccule of the laryngeal ventricule. Infection results in laryngopyocele. We report a case of laryngopyocele discovered in a patient presenting with fever, an inflammatory mass, dysphagia and minimal respiratory distress. Diagnosis was established from direct laryngoscopy and CT-scan. Early treatment consisted in antibiotics and needle aspiration followed by external excision. Laryngopyocele can sometimes be revealed by an episode of acute respiratory distress requiring tracheotomy. If there is no respiratory distress and if the infection is cured, endoscopic treatment with or without laser can be performed for internal laryngocele. The cervical approach can only be recommended for external or combined laryngocele.
