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 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.

Posterior épidural migration of a lumbar disc herniation is rare. Clinical symptoms frequently indicate severe radicular compression. ⋯ Three cases of cauda equina syndrome from posterior epidural migration of a lumbar disc herniation along with a review of the literature are presented to illustrate the Imaging features of this entity and related diagnostic difficulties. Finaly, early surgical management is the treatment of choice for optimal symptomatic recovery.
