Value of anatomical partitioning of the retroperitoneal space in determining the origin of neurogenic tumors.

ABSTRACT:

Background

To analyze the anatomical partitioning of the retroperitoneal space and determine the distribution patterns of primary retroperitoneal neurogenic tumors (PRNTs).

Methods

Retrospectively analyze the clinical data and CT data of 401 patients with single-injection PRNT confirmed by surgical pathology, including 103 cases of neuroendocrine origin, 148 cases of neuroectodermal origin, and 150 cases of peripheral nerve origin. The retroperitoneal space was divided into the anterior pararenal space, posterior pararenal space, perirenal space, and great vessel space. The anatomical location of each PRNT was determined using axial CT images, and distribution patterns of PRNTs with different pathological properties were analyzed.

Results

There were statistically sign
