Sonographic diagnosis of intussusception in childhood.

The diagnosis of intussusception was established in 26 children by sonography alone. In 23 cases barium enema confirmed the diagnosis; two cases because of longstanding intussusception and one case after intestinal anastomosis were confirmed by surgery alone; in two additional cases barium enema ruled out the sonographically suspected intussusception. No positive finding was missed by sonography, which proved to be an accurate method for the diagnosis of intussusception. The sonographic findings of idiopathic intussusception and intussusception caused by lymphosarcoma are presented.
