Primär intestinale Lymphome — Diagnosestellung mittels CT und Therapie

Abstract

Primary intestinal lymphomas are most common in the stomach. The mucosa associated lymphatic tissue (MALT)-lymphoma which is closely associated with helicobacter pylori is very well known. In most cases, these malignancies are from B-Cells origin. Another possible point of manifestation, although not well known, is the small bowel. Both tumors have enormous capabilities to enlarge in the abdominal cave. This is responding to their often asymptomatic manifestation. The symptoms, if they occur, are widespread and unspecific. Ileus, diarrhae, abdominal pain or bleeding will be observed, in rare cases also perforation or gastrointestinal or cutaneous fistulas. Diagnostic imaging often demonstrates a tumour of massive size by then, which is echopoor in the abdominal ultrasound. Our report concerns two cases of small intestine lymphomas, which were diagnosed by CT-scanning and treated in our clinic in only a short period of time. The first case was a low malignant jejunal lymphoma which was almost asymptomatic, whereas the second case had an ileus, due to compression of the intestine because of a high malignant lymphoma of the ileocecal region.
