Ascariasis is the most common helminth infection in tropical countries where it is endemic. The ability of intestinal helminths to wander through the digestive system means that it can end up in the appendix lumen and lead to appendicitis by luminal obstruction. However, this presentation is still rarely described in the literature. In fact, most of the diagnoses of roundworm associated with appendicitis are made retrospectively by the discovery of its eggs on the pathological examination of an appendectomy specimen. We report the case of a 7-year-old patient living in a tropical area who consulted for acute right lower quadrant pain. The ultrasound suspected the diagnosis of appendicitis and also revealed multiple intestinal worms including one in contact with the inflamed appendix. Surgical exploration confirmed appendicitis associated with roundworm partly in the appendicular lumen through a perforation.
