[Observations concerning an unusual presentation in a case of intestinal duplication].

Duplications of the alimentary canal are an infrequent pathology and may be localised in any part of the digestive tract. According to reports by several authors, the jejunoileal localisation is the most frequent. The authors report the case of a 13-year-old patient with a duplicate ileal tract which remained asymptomatic until hospitalisation was required, whose symptoms at onset resembled the clinical manifestations of acute appendicitis.
