Retroperitoneal fibrosis and constrictive pericarditis-IgG4 related diseases: A case report

Abstract

Retroperitoneal fibrosis (RPF) is a rare disease characterized by infiltration of inflammatory cells and deposition of thickened fibrous tissues. The present study presents the case of a 53-year-old patient treated for generalized weakness and fatigue for 1 year prior to hospitalization. A cardiac ultrasound revealed pericardial effusion that required pericardiocentesis, during which 1,400 ml serous fluid with the characteristics of an exudate was aspirated. A pericardiectomy was performed due to persistent effusion and histological examination indicated pericardial fibrosis. A thoracic-abdominal computed tomography scan revealed the presence of retroperitoneal fibrosis. The patient was treated with corticosteroids and azathioprine. Follow-up examinations showed a significant reduction in the amount of abdominal fibrous tissue and no increase in pericardial effusion 1 year following the end of treatment. The patient continues to have regular follow-up control examinations with a cardiologist and nephrologist.
