Splenic artery aneurysms are rare and occur predominantly in women. Most of them are asymptomatic until rupture. We report a previously healthy 73 year-old woman who presented with non specific symptoms: dyspepsia and constipation. Laboratory tests were normal. Subsequent examinations (ultrasound and CT) showed a large aneurysm of the splenic artery without any sign of rupture. Endovascular treatment remained successfully performed using coil embolization. During a 12-months follow-up period, the patient was a symptomatic and no evidences of complications or splenic infarction were observed on CT scans.
