a–c Intraventricular Hemorrhage (IVH); d–f Intraparenchymal Hemorrhage (IPH) without intraventricular hemorrhage. a Isolated intraventricular hemorrhage such as germinal matrix hemorrhage (GMH-IVH; arrow). b Intraventricular hemorrhage (solid arrow) with subsequent periventricular hemorrhagic infarction (PVHI; dotted arrow). c Intraventricular hemorrhage (solid arrow) with separate area of intraparenchymal hemorrhage (dotted arrow). d Intraparenchymal hemorrhage (dotted arrow) associated with a cerebral sinovenous thrombosis (CSVT), also known as a dural venous sinus thrombosis (DVST; solid open arrow). e Intraparenchymal hemorrhage (dotted arrow) in an arterial distribution suspicious for hemorrhagic transformation of an arterial infarct (Fetal Arterial Ischemic Stroke; FAIS). f intraparenchymal hemorrhage not associated with IVH, clot, nor consistent with hemorrhagic transformation of an arterial infarct suspected to be an idiopathic hemorrhage (Fetal Hemorrhagic Stroke; FHS). Illustrations are meant to reflect anatomy at ~25 gestational weeks. Refer to Fig. 2 for the corresponding proposed classification flowchart.
