Transverse scan reveals multiple layers and concentric rings of bowel within bowels and central echogenic mesenteric fat and round to oval hypoechoic mesenteric lymph nodes giving "target sign".
Longitudinal scan reveals "pseudokidney sign" which represents the invagination or telescoping of proximal bowel segments (intussusceptum) into the lumen of the next distal segments (intussuscipiens). It also shows multiple enlarged lymph nodes that have been drawn into the intussusception.
Transverse colour Doppler ultrasound reveals normal vascularisation of the invaginated bowel walls within the intussusception.
