AXR of necrotizing entercolitis
AXR AP (above) shows an extremely dilated bowel gas pattern with cuvilinear air in the wall of the entire colon. There is increased lucency in the center of the image just beneath the diaphragm. AXR left lateral decubitus (below) shows a small amount of air between the abdominal wall and the liver. There is also an extensive amount of branching air seen within the liver.

The diagnosis was necrotizing enterocolitis resulting in pneumatosis intestinalis, portal venous gas, and pneumoperitoneum.
