Initially we started with angiography as a diagnostic and possible therapeutic method that showed a diseased splenic artery with multiple SSAs, the biggest was measuring 2.5 cm in diameter, saccular in shape and located in the proximal segment of the splenic artery close to the celiac axis and the smallest was distal in the hilum nearly embedded in the parenchymal tissue of the spleen (Fig. 1).

Microscopic examination revealed non-arteriosclerotic, non-inflammatory vasculopathy with areas of smooth muscle fibers loss (mediolysis) and rupture of elastic lamina; those histopathalogical changes were suggestive of segmental arterial mediolysis (SAM) (Fig. 3).
