[Imaging of Mesentery and Omentum]

Although primary tumors in the mesentery and omentum are relatively rare, it is often necessary to distinguish them from other non-tumorous diseases. Since the omentum and mesentery are major routes for the spread of various abdominal diseases, the anatomy, type, and pattern of the diseases affecting these organs should be known in detail for accurate differential diagnosis. In addition, it is important to detect and promptly treat hidden lesions in the mesentery and omentum. Therefore, careful observation of the area where the lesion occur should be emphasized when assessing mesentery and omentum in abdominal CT.
