findings of splenic emergencies: a pictorial review. Splenic sequestration. (a) CT features of ASSC. Contrast-enhanced axial CT image of a 26-year-old male with known sickle cell-thalassemia reveals lack of enhancement in spleen parenchyma (arrow). Retrograde filling of splenic vein (arrowhead) from the portal vein can be visualized. (b) Axial T2-weighted MRI demonstrates hypointense spleen (arrows) secondary to iron deposition. Splenic vein manifests with hyperintense appearance (arrowheads) due to slow flow resulting from retrograde venous filling
