[Acute intestinal intussusception revealing intestinal T-cell lymphoma in adults]

Acute intestinal intussusception occurs primarily in infants and young children. It uncommonly occurs in adults. It can have various causes. In the vast majority of cases, it is secondary to a benign or malignant tumor. Intestinal T-cell lymphoma revealed by intestinal intussusception is very rare. We report the case of a 43-year old patient admitted with intestinal occlusion to the Emergency Department at the University Hospital Hassan II, Fes, Morocco. Abdominal CT scan showed acute intestinal intussusception associated with incarcerated bowel loop with bowel wall thickening. Treatment was based on open carcinological resection. Anatomopathological and immunohistochemical examination of the surgical specimen showed large T-cell anaplastic lymphoma. After surgery, chemotherapy was indicated to improve prognosis and to avoid a potential relapse. Intestinal intussusception rarely occurs in adults. It most often leads to the detection of an organic cause such as a tumor. This study and literature review aim to highlight the clinical and diagnostic features as well as the therapeutic approaches for this rare disease.
