A Rare Case of Retroperitoneal Fibrosis Extending into the Peritoneum: Case Report

Abstract

Retroperitoneal fibrosis (RPF) is a rare disease with an incidence de 0-1/ 100000 inhabitants per year and is associated with chronic inflammatory fibrosis of the retroperitoneum. It may be idiopathic or secondary to neoplasic or multisystemic diseases. It usually develops around the abdominal aorta and the iliac arteries, and spread into the adjacent retroperitoneum, where it frequently causes ureteral obstruction. We report in this work a rare case of retroperitoneal fibrosis extending through the superior mesenteric artery into the peritoneum. To our knowledge, no similar case is reported in the literature.
