To describe the ultrasonographic findings in different forms of jejunal intussusception in three children. Two children with hamartomatous polyps of the jejunum acting as lead points for antegrade jejunoileocolic intussusception and retrograde jejunoduodenogastric intussusception respectively and one child with idiopathic postoperative intussusception were examined by ultrasonography. The findings of the US studies were abnormal and different in each case, depending on the underlying condition and the direction (antegrade or retrograde) of the intussusception. The hamartomatous polyps were seen as hyperechoic solid masses but could not be diagnosed more specifically with US. A target lesion was found in the case of idiopathic postoperative intussusception. The US results prompted the next imaging procedure, air enema in the one patient in whom the intussusception had reached the colon and preoperative barium meal in all of the patients. Surgery was performed without the delay that usually occurs with jejunal intussusception. In the appropriate clinical setting, US should be used to look for jejunal intussusception, so that suitable diagnostic gastrointestinal studies can be performed and delay in diagnosis avoided.
