From: Subpial hemorrhages in neonates: imaging features, clinical factors and outcomes
MR image of a full-term neonates with pattern C. The subpial hemorrhage shows hypointense on T2WI and hyperintense on T1WI. Hemorrhage is seen in the underlying cerebral cortex and white matter, resulting in a hyperintense on T1WI and T2WI (a-b). There was no restricted diffusion in the subpial bleed and hyperintense on underlying cerebral cortex and white matter (c). SWI shows magnetic susceptibility artifact blurs, making it diffcult to separate the subpial hemorrhage from underlying the cortical ribbon ( d, arrowhead). This combination of a dark subpial hemorrhage collection and the bright underlying cerebral cortex and white matter forms a yin-yang sign (a and c).
