A young woman with recurrent lower respiratory tract infection.

Tracheobronchomegaly is a rare congenital abnormality with marked widening of the trachea and major bronchi, in most cases associated with chronic recurrent respiratory tract infection. We present this rare syndrome in a young woman who presented with recurrent respiratory tract infection. She was found to have tracheobronchomegaly on flexible bronchoscopy, which was confirmed with high-resolution computed tomography findings.
