Bilateral congenital emphysema: Unusual cause for recurrent respiratory tract infection.

Congenital lobar emphysema is usually restricted to one lobe of a lung. We report a rare case of bilateral congenital lobar emphysema, where the right middle lobe and its equivalent on the left side (lingula) were affected. Newer modalities of imaging (like high resolution CT scan thorax) have made the simultaneous diagnosis of bilateral involvement possible, which otherwise could be missed in a plain chest radiograph.
