Abstract
Chest radiographs and CT are especially useful for the follow-up of patients after lung resection. The purpose of this paper is to illustrate normal postsurgical imaging findings that differ according to the type of surgery (pneumonectomy, lobectomy, segmentectomy and wedge resection). Anatomic changes induced by surgery affect the remaining lung, pleura and chest wall, mediastinum and diaphragm. After pneumonectomy, there is accumulation of fluid in the post pneumonectomy space, progressive chest retraction with mediastinal shift toward the operated side and elevation of the ipsilateral hemidiaphragm. After lobectomy, there is hyperexpansion of the remaining lung, mediastinal shift and intercostal space narrowing. Theses findings are different according to the delay after surgery. Knowledge of the variable imaging features is necessary to detect complications and to provide appropriate follow-up of the primary disease.
