Recurrent lower respiratory tract infections in a 14‐year‐old boy with tracheobronchomegaly (Mounier‐Kuhn syndrome)

Tracheobronchomegaly (Mounier‐Kuhn syndrome) is characterized by dilatation of the central airways, tracheobronchial outpouchings, and chronic tracheobronchitis. Most cases are diagnosed in adulthood. We report the clinical, radiographic, and bronchoscopic findings in a 14‐year‐old boy with tracheobronchomegaly, ptosis of the right eyelid, and redundant skin and mucosa of the upper lip, who presented with a 2‐year history of recurrent lower respiratory tract infections. Pediatricians should be aware of the possibility that tracheobronchomegaly may cause clinical symptoms in childhood and adolescence. Pediatr Pulmonol. 2000; 29: 476–479. © 2000 Wiley‐Liss, Inc.
