Characterization of CT and MRI findings in sclerosing angiomatoid nodular transformation of the spleen: novel discovery of peritumoral vascular signs.

ABSTRACT:

Background

Sclerosing angiomatoid nodular transformation (SANT) is a rare benign vascular lesion of the spleen. Previous studies have described some imaging characteristics, such as centrifugal or centripetal enhancement patterns. However, comprehensive descriptions of imaging features, especially peritumoral vascular changes, remain limited. This study aimed to characterize the imaging features of SANT of the spleen, with a focus on identifying peritumoral vascular changes.

Methods

A retrospective analysis was conducted on 57 consecutive cases of SANT, including clinical, pathological, and imaging data. Imaging modalities included computed tomography (CT) scans in 41 individuals and magnetic resonance imaging (MRI) scans in 34 individuals.

Results

All 57 cases exhibi
