Iliacus hematoma associated with femoral nerve palsy is a very rare but considerable complication of hip arthroplasty. A 76-year-old woman had femoral nerve palsy 6 months after revision hip arthroplasty using a reinforcement plate. Computed tomography and selective angiography revealed the pseudoaneurysm on an extension of one of the screws fixing the hardware. Transcatheter arterial embolization proximal to the aneurysm was performed to resolve the aneurysm and to prevent further bleeding. Surgical removal of the hematoma was successfully achieved, as was full functional recovery. This case report describes our diagnosis and treatment of this rare condition and also the therapeutic usefulness of the radiologic intervention to control further bleeding before and after surgical removal of the hematoma.
