- the appendix is not identified
- within the right iliac fossa, there is the appearance of a 'doughnut sign' in trans imaging characterized by concentric alternating echogenic and hypoechoic bands as well as a 'pseudokidney' sign in long images characterized by fat-containing mesentery dragged into the intussusception
- the hyperechoic core (mesenteric fat) has a diameter exceeding that of the outer wall, which is suggestive of ileocolic intussusception
- trace volume free fluid in the right iliac fossa
- no lead point identified
Case Discussion
Intussusception is a relatively common cause of right iliac fossa pain in the pediatric population.
This patient was transferred to a tertiary pediatric hospital for further evaluation and consideration of air-enema reduction.
The site of this intussusception was not known, however both statistical probability, location and some ultrasound features suggest it is an ileocolic intussusception.
