The authors report a case of persistent sciatic artery aneurysm, which is a rare vascular congenital disease that occurs when the femoral system fails to develop or when the primitive vascular system fails to involute during embryologic development. A 60-year-old male patient presented a painless and pulsatile buttock mass for 4 months. He had no history of external trauma. Complementary tests demonstrated an incomplete and unilateral persistent sciatic artery aneurysm. The patient was submitted to proximal and distal ligation of sciatic artery, and vascular reconstruction was not performed.
