Diagnosis certain

Presentation

Abdominal distention and "red currant jelly" stools.

Patient Data

Age: 2 years
Gender: Male
ultrasound

Transverse scan shows a concentric image known as "target sign", which represents layers of mucosa, muscularis and serosa seen in intussusception appearance. The longitudinal scan show the "pseudokidney sign" that represents invagination or telescoping of the proximal segment of the bowel (intussusceptum) into the lumen of the distal segment (intussuscipiens).

Transverse Doppler ultrasound scan revealed marked hyperemia within the intussusception, indicating inflammatory process.

Furthermore, it was able to visualize multiple enlarged lymph nodes next to the intussusception.

Case Discussion

Intussusception is the invagination or telescoping of the proximal segment of the bowel (intussusceptum) into lumen of the distal segment (intussuscipiens).

The most common location is ileoileal, but it can occur in ileocolic and colocolic segments.

Ultrasound is an excellent imaging tool to make the diagnosis in children.
