Non-Hodgkin's lymphoma revealed by an ilio-colic intussusception in a Moroccan patient: a case report.

Intussusceptions are rare but well-known causes of the small bowel obstruction in adults and an underlying cause is present in the majority of cases. Lymphoma's involvement of the ileum is one of the rare causes of intussusception. CT is a sensitive examination that diagnoses intussusceptions and provides an excellent pre-operative evaluation including possible extension and dissemination especially in intestinal lymphomas. The treatment is almost always surgical and the pathological study is needed for diagnostic confirmation. Authors present an unusual case of intestinal intussusception due to lymphoma of the terminal part of the ileum in a 49-year-old man. Computed tomography confirmed the diagnosis of intussusception and non-Hodgkin's lymphoma of B-cell was diagnosed by histological examination after surgical treatment. Primary intestinal lymphomas differ from gastric lymphomas in clinical features, treatment, and prognosis. They are not well characterized and the standardized concepts for their clinical diagnosis and management are absent. The aim of this rare observation is to shed light on NHL of the small bowel, its clinical and radiological diagnosis and its treatment especially in forms revealed by intussusceptions in adults.
