Not your routine foreign body: endobronchial tuberculosis in an infant.
Foreign-body aspiration is a common cause of respiratory distress among children. Here we describe an 8-month-old, previously 34-week premature, male patient who presented with a 1-day history of fever and increased work of breathing. Of note, 3 weeks before presentation, the patient had been treated with orally administered amoxicillin for presumed pneumonia and exhibited good clinical response. No chest radiograph was obtained at that time. A current chest radiograph revealed hyperexpansion of the left lung, with a mediastinal shift. Although the patient was referred because of possible foreign-body aspiration, no clear history of an aspiration event was obtained, and computed tomographic scans of the chest were recommended. These showed extensive hilar and mediastinal lymphadenopathy, resulting in obstruction of the left bronchus. Bronchoscopy revealed a cheesy granulomatous mass in the left mainstem bronchus, which was ball-valving into the upper bronchus. Removal resulted in improvement of the patient's respiratory status. Pathology, bronchial lavage, and gastric aspirate specimens all revealed acid-fast bacilli, consistent with Mycobacterium tuberculosis infection. This unusual presentation of tuberculosis may become more common in the United States as the incidence of immigrants carrying tuberculosis increases.
