Figure 1. A chest radiography revealed elevation of the diaphragm due to dilated and gaseous intestines (a). A radiograph of the abdomen revealed diffusely dilated intestines and multiple, small radiolucent linear bubbles lining the intestines (circle) (b). Abdominal computed tomography revealed dilated and gaseous small intestines, retention of gas in the intestinal wall (circle) (c), and intraperitoneal free air (arrows) (d). Operative findings revealed small air bubbles in the intestinal wall and mesentery (e).
Figure 2. A chest radiography revealed decompression of the right lung with an elevated diaphragm and the retention of massive free air under the diaphragm (circle) (a). Non-contrast computed tomography revealed bilateral multiple emphysematous bullae in the lungs (b), distended small intestines, and intraperitoneal free air (arrows) along with multiple, small bubbly cysts beneath the intestinal serosa (circle) (c).
