Intussusception - pseudokidney sign

Discussion:

Air reduction enema was performed in this patient with plain film and ultrasound findings consistent with intussusception

An 18F Foley catheter was placed per rectum. Contrast was injected into the balloon under fluoroscopic guidance. 

Under fluoroscopy, air was introduced by the Foley catheter and outlined the large soft tissue mass within the right upper quadrant. This was then pushed into the region of the ileocecal valve into the small bowel by air reduction.
