Results: Although most cases (11/16) were typical and clearly classified on MRI, atypical cases were also observed, such as meningioma of long T1/T2 signal intensity with small cystic foci, and neurinoma of iso intensity and homogenous enhancement without cystic change or enlargement of internal acoustic meatus.

结果：尽管多数神经鞘瘤(5/8)和脑膜瘤(6/8)具有典型的MRI表现特征并仅经MRI即可得到正确鉴别，但部分病例(5/16)为不典型表现者，如脑膜瘤呈长T1长T2信号并伴有囊变，以及神经鞘瘤呈等信号、均匀强化且不伴有囊变或内听道扩大者，鉴别诊断困难。
