CTICasesEndobronchial hamartoma
Imaging findings
Chest CT shows progressive right lower lobe bronchus narrowing and mucous impaction progressing to complete obstruction and collapse of the right lower lobe over one year, with bronchoscopy demonstrating a hard mass composed of viable cartilage.
Key takeaways
Endobronchial hamartoma is a rare, benign neoplasm that can cause progressive airway obstruction, distal mucous impaction, and lobar collapse. It can grow relatively quickly, mimicking an endobronchial malignancy or foreign body aspiration, and sleeve resection can be used for preservation of adjacent lobes.
