## TL;DR

Retroperitoneal lipomatosis is a harmless condition causing gradual buildup of fat in the retroperitoneal area without abnormal density spots.

## Contribution

This paper identifies retroperitoneal lipomatosis as a distinct benign and idiopathic condition with specific imaging characteristics.

## Key findings

- Retroperitoneal lipomatosis presents as a progressive and symmetrical fat lesion.
- The condition is characterized by homogeneous fat without increased density areas.
- It is classified as a benign and idiopathic process.

## Abstract

Teaching point: Retroperitoneal lipomatosis is a benign idiopathic process resulting in a progressive, symmetrical and homogeneous increased retroperitoneal fat lesion without areas of increased density.
