MRI and CT findings of 30 patients with nasopharyngeal carcinoma invading the cerebello pontine angle 鼻咽癌侵犯小脑脑桥角MRI和CT诊断要点
Objective To study the morphology and surgical outcome of the tumor involved the fourth ventricle, brain stem, inferior cerebellar peduncle and the cerebellar pontine ( CP) angle. 目的研究第四脑室小脑脚脑干区肿瘤的形态学特点,以及安全地切除此部位肿瘤的手术方法。
The tumor of case 2 showed high signal on T_1WI, T_2WI, and fat-suppression image, most of which was in cerebello pontine angle and only a small part in suprasellar region. 例2肿瘤的大部分位于桥小脑角区,仅小部分位于鞍上,T1WI和T2WI均为高信号,脂肪抑制亦为高信号;
Microsurgical Excision of the Tumors in Cerebellar Pontine Angle Region 桥小脑角肿瘤的显微外科手术治疗
Purpose: To study the MRI of the normal anatomical structures of cerebello pontine angle ( CPA). 目的:研究桥小脑角区MRI正常解剖。
