Ruptured abdominal aortic aneurysm is life-threatening without immediate management. The initial clinical presentation is non-specific and impending rupture is easily missed, especially without a CT scan. We present a case of a 56-year-old man with low-back pain and left lower-extremity numbness, which was diagnosed as a herniated intervertebral disc (HIVD) with left acute sciatica syndrome. He also complained of persistent fever and abdominal discomfort. Routine blood work-up revealed leukocytosis and decreasing haemoglobin levels. CT angiography (CTA) showed impending rupture of the left aorto-iliac aneurysm. We therefore performed endovascular aneurysm repair (EVAR). Blood culture revealed Salmonella enterica, for which he received antibiotics. No acute sciatica syndrome was present immediately after the EVAR. No EVAR-related complications were noted in the one-year CTA follow up.
