A 39-year-old female patient with known cryptogenic cirrhosis, severe portal hypertension, and hypersplenism underwent partial splenic artery embolization. a Catheter angiography image shows the occluded upper pole branch of the splenic artery (arrow) with microparticle and coil embolization. Noted were multiple saccular aneurysms in the distal arterial branches of the lower pole (arrowheads). b Follow-up contrast-enhanced abdominal CT 6 weeks after the embolization shows large iatrogenic splenic infarction (asterisk). c Follow-up abdominal MR image 2 years after the embolization demonstrates the chronic phase of splenic infarct with a smaller size of the spleen and low T2 signal intensity within the regressed infarcted segment (arrowheads)
