Large Hiatal Hernia - A chest radiograph showed a large air–liquid shadow in the inferior retrocardiac position (Panels A and B, arrows), which suggested a large paraesophageal hernia. A computed tomographic scan showed a large retrocardiac mass containing air and liquid (Panels C and D, red arrows) that was consistent with herniation of the stomach into the chest. Thickening of the gastric wall suggested edema (Panel D, white arrow) and compression of the first portion of the duodenum, which caused gastric distention. #Clinical #Radiology #CXR #CT #HiatalHernia #NEJM
