Chronic periaortitis (CP) is a rare fibro-inflammatory disease characterized by periaortic fibrosis and/or aortic aneurysms formation, mostly localized in retroperitoneum and occasionally in the mediastinum. Recent studies have shown its common association with autoimmune diseases, therefore autoimmunity has been proposed as a contributing factor.
Herein, we describe the second case in the literature of CP associated with antiphospholipid syndrome. A 64-year-old man with history of open surgery for inflammatory thoracic aneurysm and recurrent deep vein thrombosis was referred for abdominal pain and weight loss in the last 6 months. Further investigation revealed elevated acute-phase reactant levels, positive antiphospholipid autoantibodies, radiological and histological evidence of periaortic fibrosis and inflammation causing abdominal aneurysm and ureteral obstruction. Diagnosis of CP and antiphospholipid syndrome were made and steroid therapy was implemented with clinical and radiological improvement. The present report further supports the potentially immune-mediated origin of CP, highlighting its possible linkage with antiphospholipid syndrome.
