Mediastinal tuberculosis in a 10-month-old child

Abstract

We report a rare case of mediastinal tuberculosis in a child who presented as a possible inhaled foreign body. A 10-month-old girl was admitted with a five-month history of cough, wheeze and problematic feeding, thought initially to be due to asthma. A clinical deterioration and subsequent X-rays suggested an inhaled foreign body. However, at direct laryngotracheobronchoscopy no foreign body was found and subsequent investigations revealed a subcarinal mediastinal mass. She underwent a thoracotomy and excision of the mass, the histological analysis of which revealed it to be of tuberculous origin. When a patient presents with symtoms of upper airway obstruction which are highly suggestive of a foreign body, other causes such as mediastinal tuberculosis must be borne in mind when no foreign body can be found. Although rare, cases of tuberculosis are apparently increasing and the otolaryngolgoist must be aware of its various manifestations and submit specimens for appropriate analysis. We also briefly review mediastinal lymphadenopathy due to tuberculosis.
