Subcortical hematomas develop in brain trauma and less commonly in hypertensive intracerebral hemorrhage. Six cases are reported that exhibit a spectrum of computed tomographic (CT) findings in this entity. Pathologic correlates in four cases are presented. It is theorized that subcortical hematomas form in trauma secondary to shearing stresses in the brain. Differential movement of gray and white matter may disrupt cortical medullary vessels. Rupture of degenerative vessels at this junction may account for hypertensive hematomas.
皮质下血肿在脑外伤时出现，较少见于高血压性脑出血。本文报告6例该疾病的计算机断层扫描（CT）表现。并给出了4例的病理关联。据推测，皮质下血肿在脑外伤时因剪切力而形成。灰质和白质的差异运动可能会破坏皮质髓质血管。此交界处变性血管的破裂可能是高血压性血肿的原因。
