The same patient as in Fig. 2. Axial CT in the “lung window” depicts the thoracoabdominal continuum. a The anterior blending of the endothoracic and endoabdominal fascias outlined by air: one in the midline, between the two slips of sternal origin of the diaphragm on the back of xiphoid process, and two parasagittal between the sternal and costal origins of the diaphragm—the sternocostal triangles or foramen of Morgagni. b The crura have separated, forming the oesophageal hiatus. The subpleural space of the thorax and subperitoneal space of the abdomen are in continuity through the subserous space within the oesophageal and aortic hiatus
