[Intestinal intussusception in adults, atypical and potentially dramatic].

Intestinal intussusception is essentially a pediatric pathology that remains rare in adults. We report the case of a 67-year-old patient hospitalized for persistent painful abdominal attacks despite the completion of an almost exhaustive assessment. An entero-scanner will finally show the presence of ileal-ileal intussusception, which is the site of a monoclonal plasmablastic lymphoma and responsible for an upstream sub-obstruction. This condition will require an exploratory laparotomy. As often in this pathology of the adult, the irreducible character will justify the realization of a small resection of the incriminated segment.
