Methods We retrospec-tively analyzed CT scans of100cases who suffered from cerebral hemorrhage with high-density image in brain centralis and tentorium cerebelli.

回顾性分析大脑正中部、小脑幕呈线形高密度影的脑出血病人100例。

Lateral tumors in adults often appear extraaxial and may simulate meningiomas of the cerebellopontine angle or tentorium, acoustic neuromas, ependymomas, glomus jugulare tumors or metastases, solid hemangioblastoma and choroid plexus papilloma.

位于外侧的肿瘤经常表现类似于轴位病变，与桥小脑角区或幕下脑膜瘤、听神经瘤、室管膜瘤、颈静脉球瘤或转移瘤、实性血管母、以及脉络膜乳头状瘤相类似。

CT sometimes presents with relatively high density in sinus rectus, sinus sagittalis superior, longitudinal fissure cistern and cerebellar tentorium in normal newborn infants, which easily diagnosed as newborn SAH. So it should be paied attention to the cranial CT differential diagnosis of normal neworns and newborns with SAH.

正常新生儿CT表现为直窦、上矢状窦、纵裂池、小脑天幕有时密度相对略高，易误诊为新生儿SAH，因此要注意正常新生儿颅脑与新生儿SAH的CT鉴别。

The main points of differential diagnosis between temporal lobe hernia and cerebellar tonsillar hernia.

小脑幕切迹疝和枕骨大孔疝的鉴别诊断要点。

Clinical features of HSLE were different from acute or chronic heroin toxication absolutely.

HSLE的临床表现与急、慢性海洛因中毒完全不同，主要表现为小脑性共济失调。

Objective: To improve CT diagnostic accuracy for cerebellar vermis tumors.

目的：提高小脑蚓部各肿瘤CT 诊断的正确性。

Materials and Methods:Plain and enhanced CT scanning were performed in 95 patients with surgically and pathologically proved cerebellar vermis tumors.

材料与方法： 95 例经手术、病理证实的小脑蚓部肿瘤，男性59 例，女性36例，术前均行CT 平扫及增强扫描。

From an imaging perspective, these patients have either complete or partial agenesis of vermis, which results in triangular-shaped mid fourth ventricle and a bat-wing appearance in its superior aspect.

从影像学角度来看，这些病人都会有完全或部分的小脑蚓部发育不良，这导致四脑室中部呈三角形样改变，上方呈蝙蝠翼样改变。

Cystic appearance of the posterior fossa does not always represent a Dandy-Walker spectrum anomaly. Absent vermis may be confused with Dandy-Walker anomaly, especially on prenatal ultrasound.

后颅窝囊肿并不总是代表着Dandy-Walker综合症，小脑蚓部的缺乏可能导致与Dandy-Walker异常相混淆，尤其是在胎儿超声检查中。

8 The anterior-to-posterior measurement of the cisterna magna obtained in the midline from the posterior margin of the cerebellar vermis to the inner wall of the occipital bone is approximately 5 mm.

在中线处自小脑蚓部后缘至枕骨内壁所测得的前后径约为5mm。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
