Pyolaryngocele is a very rare and serious complication of laryngocele. It can present as deep neck space infection and mislead the diagnosis. Our aim is to bring this unusual entity to the attention of surgeons and describe its clinical features.
Case Report:
We report a case of a 45-year-old male patient with a five-week history of neck swelling, dysphonia, dyspnea and odynophagia. An urgent CT scan showed a mixed pyolaryngocele. The management consisted of a high dose antibiotic and an excision of the residual laryngocele via an external approach.
A pyolaryngocele is an unusual complication of laryngocele, which becomes secondarily infected, causing many symptoms. Removing the laryngocele is still the best treatment option to prevent this complication and recurrence.
