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 tracheo bronchitis. Most cases are diagnosed in adulthood. We report the clinical, radiographic, and bronchoscopic findings in a 14-year-old boy with tracheob ronchomegaly, ptosis of the right eyelid, and redundant skin and mucosa of the upper lip, who presented with a 2-year history of recurrent lower respi ratory tract infections. Pediatricians should be aware of the possibility t hat tracheobronchomegaly may cause clinical symptoms in childhood and adole scence. (C) 2000 Wiley-Liss, Inc.
