Abstract:
Objective To evaluate the relationship between recurrent intussusception and enlarged mesenteric lymph nodes (EMLNs) in children by ultrasound.Methods A total of 35 cases (a total of 75 relapse) with imaging features of recurrent intussusception were retrospectively analysed.The sequence,size,number,morphology and location of EMLNs were recorded.Results Twenty cases of EMLNs were found in 35 cases recurrent intussusception (57.1%,20/35).At least three EMLNs were found in and / or around the mesentery of intussusception.The imaging feature of recurrent intussusception was a " target" appearance on transverse scans and a "sleeve" sign on longitudinal scans .All the EMLNs were smooth and oval-shaped hypoechoic nodule.The largest longitudinal diameter of the EMLNs ranged between 7-20 mm ,the largest transverse diameter of the EMLNs ranged between 3-8 mm with the aspect ratio≥2.0.Conclusion The Enlarged mesenteric lymph node recurrence of intussusception in children is crucial factor.Ultrasound can not only accurately and timely diagnose and treat intussusception while scanning enlarged mesenteric lymph nodes,which can provide an important basis for reducing the recurrence of intussusception.
