因血管畸形破裂造成的脑内和脑室内出血,此种血管病变(组织学上称为动静脉畸形--AVM)引起的出血可以发生在脑内或者渗入脑室或蛛网膜下隙。

The intraventricular and intracerebral hemorrhage seen here was due to a ruptured vascular malformation. The hemorrhage from such a lesion (which is most often histologically an arteriovenous malformation--AVM) can be intracerebral or extend into ventricles or subarachnoid space.

血管畸形显微镜图像显示出扩张、扭曲、类蠕虫的血管通道,这种病变可能只引起少量出血,还是癫痫发作的一个原因。

The microscopic appearance of this vascular malformation reveals the dilated, tortuous, worm-like vascular channels. Such lesions may bleed a small amount and be the cause for a seizure disorder.

CT显示右颞叶大范围出血,原因是血管畸形破裂。

This CT scan demonstrates a large area of hemorrhage in the right temporal lobe as a consequence of a ruptured vascular malformation.

因向后跌倒在大脑内出现特有出血部位,导致额叶下部和颞叶的对冲伤,出现广泛的挫伤和蛛网膜下腔出血。

The characteristic location of the hemorrhage in this brain is consistent with a fall backwards resulting in a contra coup injury to the inferior frontal and temporal lobes. This has resulted in extensive contusions and subarachnoid hemorrhage.

额叶冠状面显示累及下方脑回的广泛挫伤。此为老年人浴缸里摔倒造成的头部对冲伤。

A coronal section through the frontal lobes reveals extensive contusions involving the inferior gyri. This was a contracoup injury from a fall in the bathtub by an elderly person.

棕黄色圆齿状外观的病变与旧挫伤相一致。出血后血液溶解形成的含铁血黄素产生棕黄色外观。

The orange-brown, scalloped appearance of these lesions is consistent with old contusions. The resolution left behind hemosiderin from the hemorrhage that produces the orange-brown staining.

图示旧挫伤主要存在于额叶右下部。脑回顶部容易受到创伤外力的打击。

Seen here are remote contusions, mainly of the right inferior frontal lobe. The crests of the gyri are most susceptible to the traumatic forces.

图示车祸对头部造成大范围钝性损伤的病变。脑回挫裂伤引起出血。

The lesions seen here are the result of extensive blunt force trauma to the head in a vehicular accident. Mainly the gyri are affected with hemorrhage from contusions and lacerations.

脑桥Duret出血是继发性的,由向下压迫导致穿孔小动脉的牵拉缺血形成。各种类型损害--出血、水肿以及任一类型的肿块病变均可引起压迫性病变。

The so-called Duret hemorrhages seen here in the pons are secondary to downward compression that leads to stretching and ischemia of perforating arterioles. The compression can result from a variety of lesions--hemorrhages, edema, mass lesions of any type.

广泛的白质瘀点瘀斑是脂肪栓塞的典型表现。有趣的是,神经系统的症状和体征通常在一周后出现,例如车祸引起长骨骨折。

The extensive white matter petechial hemorrhages seen here are typical for fat embolism syndrome. Interestingly, neurologic signs and symptoms usually appear about a week after the initiating event, such as long bone fractures in a vehicular accident.
