Compensatory Lung Growth after Pneumonectomy: Case Report.

Lung expansion after pneumonectomy is well documented in animal models like dogs or mice. We present a lung expansion case after left pneumonectomy for an advanced carcinoid tumor in a 16-year-old patient with hemoptysis and acute dyspnea. This tumor was localized in the left upper lobe (LUL) invading the left main bronchus. During the follow-up we noticed a real growth of the remaining lung.
