Objective To evaluate the value of CT cisternography (CTC) in the localization of traumatic cerebrospinal fluid rhinorrhea.

摘要目的探讨CT池造影(CTC)在外伤脊鼻漏术前定位诊断的作用和价值。

Nocardia asteroides infection typically presents with an abscess or multiple enhancing lesions, with neutrophilic pleocytosis in the cerebrospinal fluid.

神经系统星型奴卡菌感染典型表现为脓肿或多发强化，有脊粒细胞增加。

Right frontal encephalomalacia The frontal pole is largely replaced with the high signal of cerebrospinal fluid left after liquifaction necrosis in this old infarct.

右额叶软化额极大部分被旧梗塞化坏死后留下的高信号脊替代。

The whole choroid fissure was clearly displayed as fissures full of cerebrospinal fluid on MRI.It go with choroid plexus of lateral ventricle congruously .

MR可清楚地显示脉络膜裂全长，表现为与侧室脉络丛走行一致的含脊裂隙。

Findings: Smooth midline cavity separating the frontal horns of the lateral ventricles (anterior to the foramen of Monro) and appearing isodense with cerebrospinal fluid.

线上位于侧室额角之间，孟氏孔之前的囊样变，与积呈等信号。
