MR scan of a 69-year-old woman who presented with a painful and pulsatile swelling at the back of her left buttock, and weakness and numbness of her left lower leg. A. An axial image at gluteal level showing an extrinsic compression of the sciatic nerve (arrowhead) by a gluteal mass (arrow). B. A coronal image at thigh region showing bilateral persistent sciatic arteries (asterisk) with aneurysmal dilatation of the left side (arrow) running along the course of the sciatic nerve (arrowhead) and giving rise to the popliteal artery.
