[Abstract] Rectal carcinoma is a common malignant tumor of digestive tract. The incidence rate has gradually increased in recent years, and the age of onset is also younger. Lymph node metastasis is a common way of metastasis of rectal cancer, and is closely related to postoperative recurrence and metastasis. Mesorectal lymph nodes are the most common and prone to metastasis. At the same time, mesenteric lymph node metastasis also affects the evaluation of circumferential margin. Therefore, preoperative diagnosis of mesenteric lymph node metastasis has very high clinical significance. However, at present, the diagnosis of lymph nodes is difficult. In addition to the overlap between metastatic and non-metastatic lymph nodes, the main point is the difficulty of postoperative lymph node follow-up. The changes of postoperative anatomical structure lead to the difficulty of image pathological lymph node location, resulting in the reduction of the accuracy of preoperative diagnosis and postoperative verification. Realizing the correspondence between imaging and pathology of mesorectal lymph nodes of rectal cancer is the key to improve the preoperative diagnosis of metastatic lymph nodes. This paper mainly summarizes the imaging and pathological corresponding methods of mesorectal lymph nodes. By comparing the advantages and disadvantages of each method, we can find a simple and reliable method to verify the preoperative imaging and postoperative lymph nodes.
