There is a tubular, hyperdense structure in the lumen of the left main bronchus which is causing almost complete obliteration of the bronchial lumen and resulting in complete collapse of the left lung parenchyma.
The mediastinum is shifted towards the left side is noted.
The right lung is compensatory hyperinflated.
Case Discussion
CT features along the clinical presentation are most likely suggestive of a foreign body with resultant left-sided, hemithorax white-out as described.
Bronchoscopy confirmed the aspiration of the cap of the pen.
Foreign body aspiration is common in the pediatric group and can present with sudden onset respiratory signs and symptoms.
