The anatomy of the mesocolon can be seen on computed tomographic (CT) scans, and its CT anatomy can be described by using the vessels in the mesocolon as anatomic landmarks. Knowledge of this anatomy is the basis to understanding pathologic processes involving the mesocolon. Common pathologic conditions usually occur due to spread of disease between organs to which the mesocolon is attached, primarily the colon and pancreas. The disease may be a malignant lesion, a benign inflammatory process, or, rarely, a primary tumor of the mesocolon; the mode of spread may be via the lymphatic vessels, direct extension, vascular invasion, or vascular involvement. The authors demonstrate various pathologic conditions and modes of spread, as seen on CT scans, with emphasis on disease of the colon and pancreas. The pathway for the spread of disease and its progression in these organs can be predicted in patients with a known disease. More important, identification of abnormalities in the mesocolon leads to careful evaluation of the organs to which the mesocolon is attached.
结肠系膜的解剖结构可在计算机断层扫描（CT）上显示，其CT解剖结构可通过将结肠系膜内的血管作为解剖标志来描述。了解这种解剖结构是理解涉及结肠系膜的病理过程的基础。常见的病理状况通常是由于疾病在结肠系膜所附着的器官之间传播所致，主要是结肠和胰腺。疾病可能是恶性病变、良性炎症过程，或者很少见的结肠系膜原发性肿瘤；传播方式可能是通过淋巴管、直接蔓延、血管侵犯或血管受累。作者展示了CT扫描所见的各种病理状况和传播方式，重点是结肠和胰腺疾病。在已知患有疾病的患者中，可以预测疾病在这些器官中的传播途径及其进展。更重要的是，识别结肠系膜中的异常会促使对结肠系膜所附着的器官进行仔细评估。
