[en] Full text: This study intends to configure an inventory of the different pathological conditions of the mesentery root using cross sectional modalities. We have made a retrospective evaluation of 42 patients; most of them had CT scans with iodinated contrast media and some of them had MRI examinations performed during 2000-2006. Our study identified a variety of pathological entities affecting the mesentery root within the study group: oedema, tumoral masses, lymphadenopathy, SMA and SMV thrombosis, etc. The imaging methods represent a valuable tool in order to establish an accurate diagnosis of this type of pathology
