1.Before backbone nerve, hind the is highlighted by film of spinal cord stiff backbone and arachnoid bursa more scabbard place when the root walks out of vertebra to be in charge of is wrapped by, call backbone film sleeve, the clearance between two scabbard and arachnoid next antrum are interlinked, nerve root is complete dip in cerebrospinal fluid, from this before, hind two wear film of classics stiff backbone severally, the scabbard that forms for stiff backbone film respectively laps, the Fu in two by there is one cranny to call backbone film pocket between putamen, this scabbard is wrapped by hind the backbone ganglion of the root.
脊神经前、后根走出椎管时多被脊髓硬脊膜及蛛网膜囊突出的鞘所包被，称为脊膜袖，两鞘之间的间隙和蛛网膜下腔相通，神经根完全浸于脑脊液中，自此前、后两根各自穿经硬脊膜，并分别为硬脊膜形成的鞘包裹，在两根的覆被硬膜之间有一裂隙称为脊膜囊，此鞘并包被后根的脊神经节。
2.Objective: To report diagnosis and treatment of 24 cases intracranial arachnoid cysts (IAC).
目的： 报告24 例颅内蛛网膜囊肿（IAC） 的诊断和治疗情况。
3.239 cases(45.3%) were diagnosed as myelomeningocele, 123 cases(23.3%) were meningocele, 107 (20.3%) were spinal bifida with lipoma, and 59 cases of spinal bifida occulta (1.2%). Surgical removal of the arachnoid cyst and lipoma relieved compression of the spinal dural sac and the tethered spinal cord.
年龄 5个月～ 4 5岁 (平均 9岁) ,其中脊膜膨出 2 39例 (4 5 3% ) ,脊髓脊膜膨出 12 3例(2 3 3% ) ,脊柱裂伴脂肪瘤 10 7例 (2 0 3% ) ,隐性脊柱裂 5 9例 (11 2 % )。
4.Results: In normal infants, the subarachnoid spaces were showed clearly, the structure was stable, the space between the arachhoid and the sulcus was 1.93～2 33 mm, and the space between the arachnoid and the gyrus was 1.44～1.64 mm. The wave structures of the sulcus and gyrus of 15 HIE infants were not clear.
结果：正常新生儿蛛网膜下腔间隙显示清晰，结构稳定，蛛网膜与脑沟之间的间隙为1?93～2．33mm，与脑回之间的间隙1?44～1?64mm，而15例HIE患儿大脑皮层沟、回结构显示不清，沟、回起伏结构消失，蛛网膜下腔间隙显示不清。
5.Arachnoid cells stimulated by hematic cerebrospinal flood can serve as antigen presenting cells to activate T-lymphocytes
血性脑脊液刺激后蛛网膜细胞激活T淋巴细胞的机制
6.Objective: To study the chordae and arachnoid granulations in the lumen of superior sagittal sinus and torcular herophili by endoscope and microscope.
摘要目的：通过内窥镜及显微镜观察成年人上矢状窦、窦汇窦腔及其内的纤维索、蛛网膜颗粒结构的解剖学形态特征。
7.Role of Air-CT Cisternograph of the CPA in Diagnosis and Treatment of Arachnoid Adhesion
Air－CT扫描对CPA区蛛网膜粘连的诊治作用
8.Methods Thirty-four patients with surgically and pathologically proved pontocerebellar tumors in which acoustic neuroms were found in 20,meningiomas in 4,trigeminalneuroms in 3,hemangioblastomas in 2,and arachnoid cyst,cholesteatoma,aneurysm,glioma,metastasis in 1 each underwent SE and FSE MR imaging before and after intravenous administration of Gd-DTPA.
方法34例经手术和病理证实的桥小脑角区肿瘤,其中听神经瘤20例,脑膜瘤4例,三叉神经瘤3例,血管母细胞瘤2例,胆脂瘤、蛛网膜囊肿、动脉瘤、胶质瘤及转移瘤各1例。 在静注Gd-DTPA前后均经SE,FSE序列磁共振成像。
9.Intracystic hemorrhage of pre-existing arachnoid cyst with adjacent subdural hematoma was found on CT and MRI of brain.
脑部计算机断层和磁振造影发现原本的颅内蜘蛛网膜囊肿出现囊内出血伴随硬脑膜下腔血肿。
10.Results Of the 100 cases,51 were acoustic neuroma,18 were meningioma,3 were trigeminal neuroma,15 were epidermoid cyst,4 were arachnoid cyst,4 were hemagioblastoma,2 were ependymocytoma,3 were cerebellar astrocytoma. Male(41 cases)and female(59 cases)are between 16～74 years old,The average age is 48.8 years.
