Traumatic inferior gluteal artery pseudoaneurysm: case report and review of literature

Inferior gluteal artery pseudoaneurysms are rare, with few cases reported in the recent literature. Such cases often present with a variable time course, mode of injury, and associated symptoms, leading to their misdiagnoses and improper treatment. We report a case of a posttraumatic inferior artery pseudoaneurysm that presented 3 months after the initial injury with a warm, tender, enlarging mass and numbness in the ipsilateral lower extremity. This article highlights the importance of placing a pseudoaneurysm in the differential diagnosis of an indurated, fluctuant, warm, erythematous posttraumatic mass, despite the absence of thrills, bruits, and pulsations.
