(Top) Transverse oblique ultrasound through the left flank shows jejunal loops with mucosal folds, valvulae conniventes. (Middle)
Transverse ultrasound through the lower abdomen close to midline shows jejunal ileal transition from a segment with folds to a

Note the lack of folds and a normal gut signature in the wall.
