Subcutaneous emphysema due to bronchial foreign body demonstrated by multidetector-row computed tomography

Abstract

Foreign body aspiration is an important cause of emergency hospital admissions in young children less than 3 years of age. It may manifest with acute respiratory difficulty, choking and wheeze acutely or may be asymptomatic. Surgical emphysema is an unusual presentation of bronchial foreign body aspiration in young children. We describe an infant with bronchial foreign body aspiration that manifested with subcutaneous emphysema and pneumomediastinum. Multidetector-row CT with virtual bronchoscopy helped in the diagnosis by detecting and localizing the intraluminal foreign body in the right main bronchus that was removed with rigid bronchoscopy.
