Chiasmatic-hypothalamic gliomas: MR imaging features and differential diagnosis

视交叉-下丘脑胶质瘤MR特征及其鉴别诊断

The small branches seen anteriorly to optic chiasma in the chiasmatic cistern were almost always the branches of superior hypophyseal artery.

在视交叉池内，垂体柄前方所见的小动脉几乎均属于垂体上动脉的分支。

Method: The primary SAH rabbit models were produced by introducing blood two times to Chiasmatic cistern through frontotemporal craniotomy.

方法经额颞开颅，视交叉池二次注血法制作兔SAH模型。

Methods Chiasmatic cisterns were observed in 15 cadaveric human heads under an operating microscope.

方法在手术显微镜下观测15个头颅标本视交叉池的显微解剖。

Simulation results showed that the achiasmatic model could provide unbiased estimations, while the chiasmatic model ( without correction) gave under estimates.

模拟结果表明，非交叉模型能提供无偏的估计值，而交叉模型则只有实际值的一半。

CONCLUSION: Optic chiasm is the center of chiasmatic cistern, which is surrounded by anterior optical nerves, posterior pituitary handle, and inferior pituitary with sphenoid saddle between them.

结论：视交叉池内结构以视交叉中心，前续视神经，后邻垂体柄，下隔鞍膈邻脑垂体等；

Operation group were made by injected autologous no-heparinized artery blood 1ml/ kg body weight into chiasmatic cistern for the first time, once again 0.5ml/kg body weight after 48 hours;

手术组采用开颅两次视交叉池注血法，首次按1.0ml/kg体重注入自体非肝素化血，48小时后按0.5ml/kg体重再次注血；
