Learning objectives To provide a basic approach for interpreting non-ischemic mesenteric pathologies. To discuss common findings associated with these conditions.
Read more Background Classically mesentery was defined as a discontinuous structure, however current concept defines it as a continuous structure with its distinctive functionality. For practical purposes, it is divided into regions which include mesenteric root, small bowel mesentery, right and left mesocolon, transverse mesocolon, mesosigmoid and mesorectum [5]. Mesenteric pathologies can be defined as primary, secondary or indeterminate.Non-ischemic mesenteric pathologies are relatively common in both hospitalised and outpatient settings. They often present with non-specific symptoms, which can lead to delayed diagnosis. These...
Read more Findings and procedure details Figure 1: Overview of non-ischemic mesenteric pathologies.Mesentery is now defined as a continuous organ, however for didactic purposes, it is divided into several regions.Figure 2: showing anatomical considerations of different regions of mesentery.Mesenteric pathologies are divided into embryological variations, non-specific inflammation,  infective and mesenteric masses:Embryological pathologies:Malrotation: These are congenital anatomical anomalies resulting from the abnormal rotation of the gut during embryogenesis. These abnormalities predispose to midgut volvulus and internal hernias.Mesenteric malrotation/ non-rotation can present in early childhood with variable presentations....
Read more Conclusion Imaging plays a vital role in evaluating non-ischemic mesenteric pathologies. The increasing use of cross-sectional imaging has led to a higher detection rate, underscoring the need for radiologists to recognise both common and uncommon imaging features to ensure optimal patient care.
