So on a CT scan, subdural hematomas follow the contour of the brain and form a crescent shape and cross suture lines.

所以在CT上，硬膜下血肿的轮廓和大脑轮廓一致，呈新月形，跨过颅缝。

Similarly, the lenses of our eyes have subtle structural imperfections called suture lines where the fibers that make up the lens meet.

我们的眼睛晶状体也相似地有一种微妙的结构缺陷——缝合线，它是构成晶状体的纤维的连接处。

Subdural hematomas cross suture lines and follow the contour of the brain forming a crescent shape, unlike epidural hematomas which don't cross suture lines and push on the brain and form a bi-convex shape.

硬膜下血肿可跨过颅缝，与大脑轮廓一致，呈新月形；相形之下，硬膜外血肿不跨过颅缝，而且压迫大脑呈双凸镜形。

Since the outer layer of the dura mater adheres tightly to the skull at sutures, epidural hematoma don't cross suture lines, and they push on the brain, forming a bi-convex shape.

由于硬脑膜外层与颅骨在颅缝处紧紧相贴，硬膜外出血不会跨过颅缝，且血肿会压迫大脑，形成双凸镜形。

Cause of death at autopsy was an embolus that dislodged from the suture line of the transplant and caused a C.V.A. With brain stem herniation.

验尸结果的死因是 移植后缝合处产生的血栓并且引起了脑疝便随着脑血管意外。
