Gastrointestinal tract is the most common location for extralymphonodular lymphomas. The small intestine is affected only in 9% of the cases. Intestinal lymphoma may have single or multiple location. This paper describes a case of multiple location in the small intestine of a non-Hodgkin B-cell in a 53 years old patient, who was initially diagnosed with bilateral pneumonia with pleurisy with E. coli, steeper on the right side, but the persistence of symptoms as fever, malaise, despite appropriate treatment, required further investigation. The CT exam observed fluid collection in the hypogastrium around a digestive loop. The patient underwent surgery, the intraoperative foundings being: a large mesenteric tumor ~ 5 cm in diameter, a terminal ileal mesenteric tumor, a mesenteric tumor ~ 6 cm in diameter, omentum with nodular formations, a tumor ~ 3.3/2.5.1 cm in the abdominal wall, pseudotumoral appendix. Segmental enterectomy with entero-enterostomy, excision of mesenteric tumors, appendectomy and omentectomy were performed. Pathological diagnosis was non-Hodgkin marginal zone B-cell MALT type lymphoma of the small intestine with extension to the appendix, meso, omentum and abdominal wall. Postoperatively, the patient received chemotherapy for remission.
