title: [Compensatory growth of residual lung after pneumonectomy in childhood].
abstract: Though pneumonectomy proved to be a potent stimulus to compensatory growth in the animal model, the literature on this subject in human patients is sparse. We report a rare case of compensatory growth after pneumonectomy in childhood. A 17-year-old man was admitted to our hospital because of chest pain. He had been capable of normal exercise despite a history of pneumonectomy at the age of 4. Chest radiography showed pneumothorax and a displaced heart. In a chest CT scan, both pleural spaces were filled with the enlarged left lung. Since thoracoscopic examination showed a bulla at the surface of S3, bullectomy was performed. The specimen resected from the lung showed slight dilatation of the alveoli. It is considered that the enlargement of the residual lung had occurred as a result of alveolar multiplication rather than by dilatation of the existing alveoli. This case demonstrates lung regeneration in childhood.
