Knowledge of the characteristic imaging features and the mechanism of internal hernia can lead to early detection and correct diagnosis, both of which can save the patient's life. This article describes common CT findings of internal hernia with emphasis on various postoperative transmesenteric hernias as well as other common internal hernias.
