Subpial hemorrhages, typically seen in neonates, are rare but can harm the adjacent brain parenchyma. The purpose of this review is to summarize the anatomy and pathophysiology of subpial hemorrhage and highlight its characteristic neuro-imaging pattern. The distinctive neuroimaging pattern of subpial hemorrhage is best appreciated on brain MRI, which shows the morphology over the cortex and injury to adjacent cortex and subcortical white matter. These findings do not occur in subarachnoid and subdural hemorrhages. Recognizing the pattern of subpial hemorrhages should guide prognostic precision, prognostication, and counseling.
脑皮层下出血在新生儿中较为常见，但较为少见，可损伤邻近脑实质。本综述旨在总结脑皮层下出血的解剖和病理生理学特征，并强调其特征性神经影像学模式。脑皮层下出血的特征性神经影像学表现最好在脑 MRI 上观察到，其显示皮层下形态学改变及邻近皮层和皮质下白质损伤。这些表现不会出现在蛛网膜下腔出血和硬膜下血肿中。认识脑皮层下出血的模式有助于提高预后准确性、预测和咨询。
