定位体征

无定位体征的高颅压综合征的CT评价

CT evaluation of increased intracranial pressure without localizing signs

无小脑定位体征的小脑梗塞临床与MRI分析

Cerebellar infarction without signs of localization : clinical and MR imaging analysis

方法68例元神经系统定位体征的癫癎大发作患者作EEG及脑CT检查。

Methods 68 patients with grand mal epilepsy without nervous systemic signs were examined by EEC and CT .

方法对30例无定位体征脑干梗塞患者行头颅MRI及双侧椎动脉超声检查，前者观察其梗塞部位、数量、大小；

Method Skull MRI and bilateral vertebral arteries ultrasound were undertaken in 30 patients with brain stem infarction without located sign .

明确的临床定位体征与术前准确的MRI成像的特征性影像相结合，是术前准确判定责任椎间隙，决定手术范围及其保证疗效的关键。

Determine surgical scope and to guarantee therapeutic effect are closely depended upon the clinical localization of lesion and preoperative exactly MRI characteristics .

目的探讨无神经系统定位体征的癫癎大发作患者的脑电图（EEG）和脑CT变化。

Objective To explore the changes of computed tomography ( CT ) and electroencephalogram ( EEG ) in patients with grand mal epilepsy without nervous systemic signs .

SCI无明确的神经系统定位体征，确诊依赖于影像学检查。

There was no definite focal neurological signs in patients with SCI , final diagnosis of SCI must depend on imageology detection .

目的应用头颅MRI及彩色超声多普勒观察无定位体征脑干梗塞部位、大小及双侧椎动脉形态结构和血流动力学变化。

Objective To observe the region and size of brain stem infarction without located sign , form and structure of bilateral vertebral arteries and dynamics change in blood flow with skull MRI and colour ultrasonic Doppler .

结论：高位脊髓型颈椎病神经系统障碍表现严重，但神经系统定位体征不十分明确。

Conclusion : High level cervical spondylotic myelopathy characterized as serious disability of nerve system .

出现偏瘫等定位体征的比例低于中老年组；

There were less patients with hemiplegia and other level physical signs in the young people group .

结论头痛、烦躁、神经系统定位体征是脑静脉窦血栓的常见症状和体征。

Conclusions headache , restlessness and focal neurological signs are the common sings and symptoms of patients with cerebral sinus thrombosis .

结论：颅内肠源性囊肿除具有压迫邻近结构的神经定位体征外，常具有以下特点：①多见于儿童或青少年；

Conclusion : Except for having localization of neural signs , intracranial enterogenous cysts are usually characteristic of : ① Often see in children or adolescent ;

3结果本病早期多以头痛、呕吐等高颅压症状起病，然后逐渐出现局灶性神经系统定位体征；

Results The disease occured with the high intracranial pressure symptome-headache and vomitting in early period , then gradually appeared fix sighs of nervous system in local site .

腰椎极外侧椎间盘突出，以坐骨神经放射痛为主，腰痛轻微、抬腿试验可以阴性，可有上位或下位神经根受压定位体征；

Extreme lumber disc herniation mainly showed radiating pain of sciatic nerve , besides slight lumbago , negative Bragards test and location sign of pressure epistatic or inferiority nerve root .

有偏瘫等定位体征者青年组9例，中老年组107例，（P<0.05）。

There were 9 cases , with hemiplegia and the other level physical signs in the young people group and 107 cases , in the other group ( P < 0.05 ) .

认为它具有早期出现贫血，意识障碍加重，发展缓慢，神经定位体征出现较晚，癫痫发生率高等临床特点。

It is considered that this disease has the following characteristics : occurence of anemia at the early stage , exacerbation of disturbance of consciousness , gradual progress , late occurrence of signs of nervous location and high incidence rate of epilepsy .
