Abstract:
Objective To observe ultrasonic manifestations of secondary intussusception (SI) in children. Methods Preoperative ultrasonic features of 125 children with histopathologically proved SI were retrospectively analyzed. Results Concentric circle sign in transverse section, sleeve sign in longitudinal section and abnormal mass echoes in intussusception loop were found in all 125 children. Low echo mass with small or round-shaped anechoic area was found in 28 children with juvenile polyps and 2 with juvenile polyposis syndrome. Wheel-like mass, radial distribution or high and low echo interphase were detected in 19 Peutz-Jeghers syndrome children, while cystic mass with thick wall showing "double ring" or "three ring" signs was found in 18 intestinal duplication children. Nodular changes or abnormal patterns of intestinal echo were observed in 17 children with Meckel's diverticulum. Obviously thick wall with rich blood supply was found in 11 children with allergic purpuras. Tubular hypoecho was detected in 6 appendicitis children. An extremely hypoechoic mass with abundant blood was noticed in 5 intestinal lymphoma children, while a mass of mixed echogenicity containing several small cystic areas was found in 2 ileal adenomyoma children. A mass echo was found in 2 lipoangioma children. A medium and high echo mass with low echo and anechoic area was found in 1 child with duodenal Brunner's gland adenoma. A mass with honeycomb microcystic margin was observed in 1 child with mesenteric lymphangio-cavernoma. A heterogeneous hypoechoic mass was found in 1 multiple polypoidal cavernous hemangioma child. A cystic mass with separation was found in 1 intestinal wall and mesentery vascular malformation child. An oval hypoechoic mass was detected in 1 child with low grade malignant angiogenic tumor. Thickened intestinal wall and lacked blood supply was found in 10 hemorrhagic necrotizing enterocolitis children. Conclusion Ultrasonography can be used to confirm original disease of SI in children, therefore provide important basis for clinical diagnosis and treatment of SI.
