Supine AP abdomen radiograph of a young boy (NOT with HSP) shows a RUQ mass (black arrows), representing an intussusception.
Central ring of hypoattenuation (arrowheads) corresponds to mesenteric fat in the intussusceptum. There is no small bowel dilatation or
radiographic evidence of small bowel obstruction.
a) This imaging finding is consistent with the diagnosis of intussusception.
b) This imaging finding is consistent with the diagnosis of appendicitis.
c) This imaging finding is consistent with the diagnosis of a kidney stone.
d) This imaging finding is consistent with the diagnosis of a liver abscess.
