Abstract

Retroperitoneal fibrosis (RPF) is a rare, progressive disease characterized by chronic non specific inflammation of the retroperitoneum. Although the pathogenesis of idiopathic retroperitoneal fibrosis (IRF) remains unclear, IRF has been reported in association with autoimmune disorders. However, few cases of IRF associated with rheumatoid arthritis (RA) have been reported. We experienced a rare case of IRF in a patient with RA and chronic B viral hepatitis. A 39-year-old Korean man with RA and hepatitis B was referred to our hospital due to left hydronephrosis. An abdominal computed tomography (CT) scan and magnetic resonance imaging (MRI) showed a diffuse infiltrating retroperitoneal mass around the abdominal aorta and left ureter. The patient underwent intraureteral stent insertion and was treated with corticosteroid. Three months later, the follow up abdominal CT showed that the retroperitoneal mass had decreased in size. Herein, we report the first case of coexistent IRF, RA, and chronic B viral hepatitis with a literature review.
