[Lymphoma as a cause of ileocecal invagination in children].

The authors describe the case-history of two ileocaecal invaginations in young children caused by a tumour of the lymphatic system. Rapid diagnosis, using sonography, contributed to a successful surgical solution of the acute abdomen as a prerequisite of early antitumourous treatment. The authors analyze possible causes of invagination focused on the tumourous etiology of this disease so serious in child age.
