A Teenage Boy with Abdominal Pain and Vomiting

Abstract

This diagnostic image presented a plain abdominal radiograph and ultrasonographic findings from a case of intestinal ascariasis, which is a relatively common cause of abdominal symptoms in developing countries. The plain x-ray highlighted soft tissue mass within the small bowel which could be accompanied by features of intestinal obstruction. The ultrasound study depicted triple-parallel lines or four-parallel lines which are characteristics of the roundworm.
