Abstract：
:The main neonatal stroke syndromes discussed in this article are: arterial ischemic stroke (AIS), including perinatal AIS, and "presumed" perinatal AIS; cerebral venous thrombosis, including cortical vein and venous sinus thrombosis and germinal matrix hemorrhage/periventricular hemorrhagic infarction; and intraparenchymal hemorrhage. This review discusses general pathophysiological mechanisms and the role of imaging in these conditions.
