Imaging description Morgagni hernia is an uncommon hernia resulting from a defect in the diaphragm's attachments to the sternum and costal cartilages with herniation of abdominal content into the anterior thorax [1, 2]. It more commonly occurs on the right due to the protective barrier effect of the heart on the left [1, 2]. On CT, the Morgagni foraminal defect is demonstrated by the lack of right and left diaphragmatic muscle fibers joining together to insert on the xiphoid  (Figure 70.1). The hernia most commonly contains omentum but may contain colon, stomach, liver, or small intestine [1, 2] (Figures 70.2–70.4).
