In two similar cases of irreducible intussusception with wall necrosis and perforation, symptoms had begun 24 h before admission and the plain radiographs showed signs of small-bowel obstruction. The sonographic (US) appearances, however, were different: color Doppler (CD) US showed vascular flow in the intussuscepted bowel in one case and no flow in the other. After radio-clinical assessment, both children underwent surgery and an intestinal resection had to be performed, manual reduction being impossible. The reliability of the US findings and the prognostic value of CD and power Doppler US in determining the viability of the intussuscepted bowel are discussed with a review of the literature.
We present a 7-month-old boy with a giant abdominoscrotal hydrocoele associated with right leg oedema. US revealed an abdominoscrotal fluid-filled mass with a normal testis in the scrotum. MRI allowed precise delineation of the mass while MRA sequences showed extrinsic compression of the right iliac vein and its patency. Hydrocoelectomy and laparotomy were performed and confirmed the diagnosis. US followed by MRI are often necessary to diagnose and delineate giant hydrocoeles. MRA is a non-invasive elegant tool for the detection of vascular complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
