Coin Aspiration Presenting as Chronic Cough and Tracheoesophageal Fistula.

Chronic cough can be a diagnostic challenge in the pediatric population. Foreign body aspiration without typical signs and symptoms can often be overlooked as a cause of chronic cough in children. Coin aspirations in the trachea typically have a sagittal orientation on an anteroposterior (AP) chest radiograph. We report a rare case of a previously healthy five-year-old girl presenting with a chronic cough for five months caused by a coin with a coronal orientation on an AP chest radiograph. The coin, initially presumed to be lodged in the esophagus, was actually lodged in the cervical trachea, leading to the development of a tracheoesophageal fistula (TEF). Her AP chest radiograph showed a coronal, circular radio-opaque shadow and the lateral view a tangential radio-opaque shadow, prompting an initial evaluation by esophagogastroduodenoscopy, which was normal. She then underwent rigid bronchoscopy, revealing a coin lodged in the trachea along with a TEF. Surgical removal was achieved through an external approach with a vertical tracheotomy and insertion of a tracheostomy tube. Five days later, a repeat rigid bronchoscopy showed a well-healed TEF, and she was successfully decannulated. She was ultimately discharged home on room air and oral feeds. TEF as a complication of a foreign body lodged in the trachea or esophagus is rare but life-threatening. Foreign body aspiration should always be considered in the differential diagnosis when evaluating younger children with chronic cough.
