Representative imaging scans of a 7-year-old male patient presenting abdominal pain. A, B: Ultrasound scans visualizing an IAH complicated with intestinal dilation and obstruction, thickening of the intestinal wall, liquid exudation in the surrounding intestinal space, and a “cross sign” ( white arrow) of the adhesive bands in the dilated intestinal tubes. C, D: Coronal and sagittal CT scans of the abdomen showed dilatation of intestinal cavity in the left middle and lower abdomen, intestinal effusion, thickening of intestinal wall and visible gas accumulation. The obstruction point (white arrow) was visualized, where the intestinal tube was entangled with the hyperechoic mesentery. E: Intraoperative manifestations of an IAH, including the banding between the beginning of jejunum and the ileum, twisted proximal intestine, extensive adhesion between the small intestine, and a C ring at the adhesive bands (white arrow)
