Vascular prosthetic graft infection is a rare but severe complication following aorto-bifemoral bypass surgery and may present with nonspecific clinical and imaging findings. Retroperitoneal fibrosis surrounding the vascular prosthesis represents an uncommon manifestation. We report the case of a 64-year-old man with prior aorto-bifemoral bypass performed four months earlier for stage IV peripheral arterial occlusive disease who presented with purulent discharge from the distal anastomotic scar associated with inflammatory biological syndrome. CT angiography demonstrated a left inguinal perigraft collection with circumferential peri-prosthetic soft-tissue infiltration extending along the graft tract with retroperitoneal extension. These findings were suggestive of periprosthetic infection complicated by secondary retroperitoneal fibrosis. Early recognition of these imaging features is essential for prompt therapeutic management [1].
