The presence of abnormal amounts of fluid in the subdural space has been referred to as subdural hematoma, subdural effusion and subdural hygroma. These are supposed to be differentiated by the appearance of the fluid and the presence of membranes in the dubdural space. Although both hygroma and chronic subdural hematoma are liquid, space-occupying lesions which cause pressure in the underlying brain, we have found that there are definite angiographic, clinical and prognostic differences between them. These differences are described.
硬膜下间隙中存在异常量的液体被称为硬膜下血肿、硬膜下积液和硬膜下蛛网膜囊肿。这些情况应根据液体的外观以及硬膜下间隙中隔膜的存在来进行区分。尽管蛛网膜囊肿和慢性硬膜下血肿均为占据空间的液体性病变，会对其下方的脑组织造成压力，但我们发现它们在血管造影、临床及预后方面存在明确差异。现将这些差异予以描述。
