(A) Abdomen ultrasound. The target (donut) sign found in the left lower quadrant, confirming the diagnosis of intussusception. (B) Hydrostatic reduction of intussusception using Gastrografin  contrast solution showing the successful reduction of the ileocolic invagination.

Due to patient's age and clinical presentation, an abdominal ultrasound was performed, showing the presence of a massive ileocolic intussusception, with increased thickness of the intestinal wall and accompanying mesentery, and enlarged lymph nodes (Figure 1A). A subsequent contrast enema, using Gastrografin  (diatrizoate meglumine and diatrizoate sodium solution) diluted with saline, was successfully performed reducing the invagination (Figure 1B).
Hydrostatic reduction of intussusception using Gastrografin  contrast solution (A). The first imaging shows the recurrence of the intussusception in the splenic flexure. (B,C) Show the relapses of the intussusception in the ascending and then back in the transverse colon, respectively.

A new non-surgical hydrostatic reduction procedure was attempted but several relapses occurred during this procedure (Figure 2).
