Splenic Infarction

    Splenic infarctions are segments of tissue necrosis, typically resulting directly from occlusion of splenic endartery vessels. The unique nature of vascular supply to the spleen dictates embolic occlusion of a non-communicating artery in the splenic parenchyma.

    Causes of splenic infarction are various, ranging from distant embolization from cardiac arrythmia, systemic vasculitis, atherosclerotic plaque rupture, splenic artery aneurysm, pancreatitis, malignant neoplasm seeding or sickle cell disease. The architecture of splenic infarcts typically resemble a "wedge" of parenchymal necrosis and the distribution, dependent on the underlying etiology, can result in multiple lesions.
