Answer

Focal postobstructive bronchiectasis may occur in a number of clinical settings (eg, endobronchial tumors, broncholithiasis, bronchial stenosis from infections, encroachment of hilar lymph nodes, foreign body aspiration). Right-middle lobe syndrome is a specific type of bronchial obstruction that may result in bronchiectasis. It results from an abnormal angulation of the lobar bronchus at its origin, predisposing it to obstruction, subsequent infection, and development of bronchiectasis.
