Mycotic pseudoaneurysm of the superficial femoral artery in a patient with Cushing disease: case report and literature review.

Mycotic pseudoaneurysms of the peripheral arteries are rare and can occur as an extension of localized infection or from systemic sepsis. In some cases, no obvious source of infection may be identified. Both endovascular and open surgical management options are available for this important condition. We report a mycotic pseudoaneurysm of the superficial femoral artery in a patient associated with systemic immunosuppression secondary to Cushing disease that was successfully managed with open surgical repair and autologous bypass grafting. This unusual case highlights the potential for serious adverse cardiovascular sequelae of Cushing disease and the need for awareness of such complications in this patient group.
