SUMMARY

Tracheal diverticulum: an unusual cause of chronic cough and recurrent  respiratory infections

Tracheal diverticulum (TD) defined as a typical benign out-pouching of the tracheal wall due to structural weakness, congenital or acquired in origin, resulting in paratracheal air cysts. It is rarely diagnosed in clinical practice with only limited reports in the literature. Most cases found incidentally in the postmortem examination and located on the right side. Uncomplicated TDs are usually asymptomatic and when symptoms have occurred, they usually present with non-specific symptoms like pharyngeal discomfort, cough, dyspnea, and recurrent respiratory infection due to either the compression of adjacent organs or secondary bacterial infection. Imaging techniques like thoraco-cervical multi-slice spiral computed tomography (CT) and fiber-optic bronchoscopy are important diagnostic tools for this entity. Asymptomatic TDs usually require no treatment and managed conservatively while surgical excision is indicated in cases of compression of adjacent organs and recurrent infections. Here we report a case of tracheal diverticulum on the left side, which was diagnosed as part of a work-up for chronic cough and recurrent chest infection in a 40 year old female who was already on bronchodilator without any relief. Diagnosis of TD was based on findings of computed tomography, revealing small bud like projection on left para tracheal region and further confirmed by fiber-optic bronchoscopy while the barium contrast study showed no esophageal communication. She was managed conservatively and referred for surgical excision.

Key words: Tracheal diverticulum, chronic cough, fiber-optic bronchoscopy
