Paediatric- IntussusceptionCreated OnMay 7, 2020Last Updated OnOctober 26, 2020byadmin You are here: Main Radiology Paediatric- Intussusception < All Topics Table of Contents Abdominal X-Ray Abdominal Xrays are NOT sensitive or specific Some suggestive features: Soft tissue mass surrounded by a crescent of gas (upper right quadrant) Evidence of distal small bowel obstruction (air-fluid levels and bowel dilation proximal to it) Absence of or decreased gas in the colon Pneumoperitoneum May be normal Soft tissue sausage shaped density in the middle of the film reflecting intussusception. Notable are a dilated small bowel and the absence of colonic gas, in a child with intussusception shows small intestinal obstruction. Ultrasound Transverse: Target or doughnut sign, with hypoechoic rim (edematous bowel wall) surrounding hyperechoic central area (intussusceptum and associated mesenteric fat) Longitudinal: Sandwich, trident or hayfork sign, with layering of hypoechoic bowel wall and hyperechoic mesentery Oblique: Pseudokidney sign, with hypoechoic bowel wall mimicking the renal cortex and hyperechoic mesentery mimicking the renal fat Doppler may help determine viability of the tissue Characteristic findings of intussusception, with a target sign and prominent lymph nodes presumably acting a lead point. Barium enema (diagnostic and therapeutic) “Coiled spring” appearance Barium in lumen of the intussusceptum and in the intraluminal space Image: Black arrow depicts intussuception being reduced by barium past hepatic flexure or large bowel. *Some of the image photo is taken from web, we do not own this, it’s for knowledge sharing purpose.
