脑桥小脑的

The suboccipital retrosigmoid approach was used on 10 adult head specimens which were fixed and perfused with color silicon, the neurovascular structures and their relationship in cere- bellopontine angles were observed under the operative microscope and endoscope.

选择经10％福尔马林充分固定，血管内灌注混有红、蓝染料的乳胶，不分性别的成人尸头10具，模拟目前临床上最长使用的枕下乙状窦后入路，在手术显微镜和神经内窥镜下，观察小脑桥脑角内的神经血管结构，确认这些神经血管的走行及其之间的解剖关系。

Results MRI findings of central neurocytoma are specific in 5 cases. The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case, cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases, obviously thickened gyri were revealed in 1 cases and central necrosis in 2 cases.The 3 cases of Lhermitte-Duclos disease include the specific molecular layer imaging features.

结果 5例中枢神经细胞瘤有一定的MRI特征，3例诊断正确。8例神经节细胞胶质瘤中，7例位于或主要位于颞、枕叶，1例位于桥脑和延髓，表现为囊实性者5例，实性部分位于囊外的有3例，呈实性表现为局部脑回增厚者1例，囊变坏死明显者2例。3例小脑发育不良性节细胞瘤有特征性的条纹状或分层状表现。

The common anatomic sites of this type of hemorrhage are, in order of frequency: putamen, thalamus, cerebellum and pons.

出血的解剖位置根据发作的频率高低依次为壳，丘脑，小脑以及脑桥。

Methods Since 1995,1210 cases （including 67 cases of tumors） of trigeminal neuralgia had received the operation of nervous decompression and combing by approach of postauricular suboccipital to the cerebellopontine angle.

回顾性 分析 1210例三叉神经痛患者的临床资料，采用经内镜下耳后小切口乙状窦后入路小脑脑桥角显微血管减压梳理术式或

The brain stem lesions observed on MRI were most commonly at the tegmentum of the pons (18/25, 72%) followed by the medulla oblongata (15/25, 60%), and the midbrain which includes the tegmentum, substantia nigra and superior cerebellar peduncles (11/25, 44%).

二十五例在急性期接受磁振造影检查的病童中，有十八例发现在脑干和上颈脊髓有T2高讯号病灶，病灶发现频率依序分别为：桥脑（18/25，72%），延脑（15/25，60%），中脑（包括脑盖，黑质区和上小脑脚）（11/25，44%）。

Artery of vertebra ? base is mixed in cerebella the branch of bridge head, supply the blood of cerebella and bridge head.

椎？基底动脉在小脑和桥脑的分支，供应小脑和桥脑的血液。

Objective:To evaluate the diagnostic value of ENG in occupied lesions of cerebellopontine angle.

目的：为了深入研究眼震电图对小脑桥脑角病变的诊断价值。

Results The clinical manifestations of TOBS comprised transient unconsciousness, vertigo, dyskinesia of eyeball, abnormality of pupils, dyskinesia of limbs, hemianopsia or cortical blindness, ataxia and memory impairment. MRI showed the local infarction in thalami, cerebellum, midbrain, pons, occipital lobe, temporal inner surface. The features of DSA were occlusion or stenosis in basilar artery and vertebral artery.

结果 TOBS的临床主要表现为一过性意识障碍、眩晕、眼球运动障碍及瞳孔的变化、肢体运动障碍、偏盲或皮质盲、共济失调及记忆功能损害；磁共振显示梗死灶在丘脑、小脑、中脑、脑桥、枕叶、颞叶内侧面；数字减影血管造影显示为基底动脉及椎动脉闭塞或狭窄。

In the pontocerebellar space, when CT plain scan were enhanced, the infarctional vessel obviously became thicken, which was reliable

例，CT 平扫见桥脑小脑间隙处一个长条环状血管影。增强时，其阻塞血管明显增粗、致密强化，这是诊断小脑前下动脉梗塞的

Early diagnosis of asymptomatic cerebral infarction is difficult, we analyzed the clinical features of 56 cases of ACI, MRI shows small lesions in relative silent area of brain stem, 85.7% of which in pons.

无症状脑干梗死早期诊断困难，为对其早期诊断，笔者分析了56例无症状脑干梗死的临床特点，MRI显示病灶小、相对静区，桥脑多见，占85.7%，且多合并半球梗死，占92.5%，或小脑梗死占10%，高血压、心脏病、糖尿病为其主要危险因素。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
