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 pathologies may arise primarily from the mesentery or involve the mesentery secondarily, with potential multicompartment and multisystem involvement. Primary mesenteric pathologies arise from mesentery primarily and involves other organs however in secondary mesenteric pathologies, disease arise outside the mesentery and progresses to involve it secondarily.

Mesentery can be involved by multiple infective, inflammatory conditions, congenital lesions or neoplastic lesions and presents as diverse imaging appearance. Unlike parenchymal organs, there is delayed presentation in most cases with no specific clinical signs, making radiologist a very important link in making the diagnosis.

Thus it becomes important for radiologist to know possible presentations of different mesenteric pathologies. We present a range of cases with diverse diagnoses and imaging appearances.  Through our poster we have also highlighted distinct teaching point in each slide, which are helpful reaching the diagnosis.
