CT research of the depression of occipital arachnoid granulations

枕骨蛛网膜颗粒压迹的CT研究

Arachnoid granulations were manifested low density in CT , 3 of them with calcification .

病灶在CT影像中均表现为低密度影，其中3个有钙化灶。

Finally , pathological section of arachnoid granulations and lamellar chordae were obtained to observe the minute structure .

最后于蛛网膜颗粒及板层状纤维索处作病理切片观察细微结构。

The location of the arachnoid granulations in cranial cavity and the apoptosis after subarachnoid hemorrhage in rats

大鼠蛛网膜颗粒在颅内的分布及蛛网膜下腔出血后的改变

16 arachnoid granulations were found , with the smallest diameter of 1.2 mm , maximum diameter of 6.2 mm .

直窦内发现蛛网膜颗粒16个，最小直径1.2mm，最大直径6.2mm。

Finally , the sinuses were opened for direct observation of the chordae , arachnoid granulations and torcular herophili using standard anatomical methods .

并纵行剖开管腔，显微镜下观察纤维索、蛛网膜颗粒及窦汇区解剖。

The parts of dural sinus were cut off and embedded with paraffin and section . The apoptosis of arachnoid granulations cells was tested by the TUNEL method .

取硬脑膜窦进行石蜡包埋、切片，采用TUNEL法检测蛛网膜颗粒的细胞凋亡。

( Results ) There were 9 arachnoid granulations found in the 8 patients . 6 of them were located in transverse sinus while 3 in superior sagittal sinus .

结果8例患者中，脑静脉窦内蛛网膜颗粒共有9个，其中6个位于横窦，3个位于上矢状窦。

Objective To find the location of arachnoid granulations in cranial cavity of rats and to analyze the apoptosis of arachnoid granulations cells by the animal experiments model of the subarachnoid hemorrhage ( SAH ) .

目的研究大鼠蛛网膜颗粒在颅内的分布，为实验取材及其相关研究奠定基础。通过动物实验分析蛛网膜下腔出血（SAH）后的蛛网膜颗粒细胞凋亡。

Methods 5 cranium specimen . After removal of the cranial roof , endoscopes were inserted into the lumen of the sinus to observe the structures of chordae and arachnoid granulations .

方法成人头颅标本5具，去除颅盖，应用内镜观察研究上矢状窦窦腔内纤维索及蛛网膜颗粒的原始结构特征；

Characteristic findings of occipital arachnoid granulations on CT were semiorbicular or semilunar depression of occipital inner table , or a punched-out like bone defect from the inner table into the outer table .

枕骨蛛网膜颗粒压迹在CT上表现为半圆形、半卵圆形或浅弧形，少数可呈穿凿样骨质缺损，深达板障或外板。
