Ascaris lumbricoides is the most common helminth affecting humans. It is endemic in tropical and underdeveloped countries. It particularly infects children but most often is asymptomatic. Sometimes, it can mimic a surgical abdominal emergency. When it is suspected, its diagnosis is made on the parasitological examination of stool. We here report the case of a diagnosis of intestinal ascariasis made on ultrasound in an 8-year-old child who consulted for an acute abdominal syndrome which initially suggested an acute intussusception.
