We report a surgical case of abdominal aortic aneurysm (AAA) and right internal iliac artery aneurysm (IIAA) causing sciatica-leg pain that starts in the lower back and travels down the sciatic nerve. A 74-year-old woman was referred to our hospital for aneurysmal repair. Her chief complaint was sciatica on the right leg. Preoperative computed tomography showed an AAA (maximal diameter of 50 mm) and right IIAA (maximal diameter of 54 mm). The AAA was replaced by an artificial graft and the IIAA was ligated and plicated. Her sciatica totally disappeared after surgery. When we see those with sciatica, we should rule out IIAA. The symptoms due to nerve compression by an aneurysm can be reversible after aneurysmal repair.
