ultrasound

Transverse US shows concentric alternating echogenic and hypoechoic bowel walls keeping with target sign of Intussusception. Found to be of ileocolic type.

The original abdominal radiograph was read negative. With high suspicion for intussusception, an ultrasound was performed. The intussusception was within the right lower abdomen, and in retrospect likely represents the soft tissue density on the abdominal radiograph as described above.
