We report two cases of superior gluteal artery aneurysms successfully treated with coil embolization and review treatment options for these lesions. Our experience in the treatment of three total aneurysms, two likely post-traumatic in etiology and one mycotic, suggests that endovascular therapy is an effective alternative to open surgery when treating superior gluteal artery aneurysms.

These lesions are often unilateral and most commonly due to pelvic trauma. 1 We describe two cases of superior gluteal artery aneurysms: one patient with bilateral post-traumatic aneurysms and one patient with a unilateral mycotic aneurysm. Both cases were successfully treated with endovascular therapy. Subsequently, we discuss the incidence, etiology, and treatment of superior gluteal artery aneurysms.
CASE 1A 75-year-old man was transferred emergently to our institution with a large actively bleeding hematoma in his right buttock. The patient had fallen earlier while in the bathroom and developed a red, warm, fluctuant mass palpable around his right buttock. He was initially seen at an outside facility, and the mass was believed to represent an abscess. Incision and drainage of the mass was attempted in the emergency room. After a liter of blood had been drained, the procedure was aborted and the site was surgically packed. The patient was resuscitated with 8 units of packed red blood cells and 4 units of fresh-frozen plasma, and he was transferred to our institution.Further information obtained from the patient's family revealed that the patient had a history of bilateral internal iliac artery aneurysms for which he declined
