Linear infarct
NettetThis type of infarcts take a linear/ cylindrical distribution extending from the pial surface toward the ventricular wall. In our experience, this type of infarcts have rarely been seen on MR images in cases with a sporadic infarct, intravascular lymphoma ( Figs. 14 and 15 ), and after surgical treatments ( Figs. 16 - 18 ). Nettet11. feb. 2024 · Watershed cerebral infarctions , also known as border zone infarcts , occur at the border between cerebral vascular territories where the tissue is furthest from arterial supply and thus most vulnerable to reductions in perfusion. Epidemiology Watershed cerebral infarction accounts for 5-10% of all cerebral infarctions 8.
