Successful reduction of intussusception by pneumatic enema

Three-year-old girl undergoing pneumatic enema reduction for intussusception.
(A) Air serves as a negative contrast, leaving the intussusception visible as a soft tissue meniscus density in the ascending colon (thin arrow). The tip of the enema nozzle can be seen within the rectum (thick arrow).
(B) Following successful pneumatic reduction of the intussusception, there is resolution of the prior soft tissue density in the ascending colon, and air is now identified within the ileum and distal small bowel.
