Although considered rare pathologies, splenic artery aneurysms are more frequently diagnosed today owing to modern imaging systems. The splenic artery is the most frequent site of this lesion, accounting for over 60% of all visceral artery aneurysms. In particular, 0.2-0.8% of the general population is affected by this pathology, although the incidence in females is four times higher than in males. The relationship between the frequency of this pathology and the female sex has been correlated with alterations occurring in the splenic artery during pregnancy, characterised by rupture of the internal elastic lamina, fragmentation of the elastic fibres and the accumulation of proteoglycans in the tunica media. We report a case of splenic artery aneurysm in which failure of the first embolisation procedure using tungsten coils called for subsequent treatment with platinum coils two months later. In addition to completing the embolisation of the aneurysmatic sac, this led to the occlusion of the splenic artery proximal to the aneurysm. Owing to the fact that angiography, colour Doppler ultrasonography and angioMR had shown adequate splenic perfusion through collateral branches, the organ was conserved without resorting to surgical removal.
