Description
Distinguishing vascular inflammation from other retroperitoneal pathologies can be challenging, particularly in patients with a prior history of Retroperitoneal Fibrosis. Iliac vessel vasculitis is an uncommon condition that may present with nonspecific abdominal or groin pain, making accurate diagnosis essential for timely treatment. We report a case of a 63-year-old male with a history of retroperitoneal fibrosis who presented with several weeks of intermittent left groin and lower abdominal pain accompanied by nausea, decreased appetite, chills, and diaphoresis. Given his prior history, recurrence of retroperitoneal fibrosis was initially considered. However, cross-sectional imaging demonstrated inflammatory changes localized to the iliac vessels, raising concern for large-vessel vasculitis. Laboratory evaluation supported an inflammatory process. The patient was treated with systemic corticosteroid therapy using Prednisone, resulting in marked symptomatic improvement and stabilization of the inflammatory findings.
This case highlights the importance of differentiating iliac vessel vasculitis from recurrent retroperitoneal fibrosis in patients presenting with groin or abdominal pain. Early recognition and corticosteroid therapy can lead to favorable clinical outcomes and prevent vascular complications.
