We retrospectively studied 21 cases of histologically proven acoustic shwannomas with an emphasis on the correlation of their magnetic resonance imaging (MRI) findings and histological features. All cases were of low signal intensity in the T1W MRI. In the T2W MRI, 9 of them were of homogeneous high signal intensity (Hom-HSI-T2) and 12 of them were of heterogeneous high signal intensity (Het-HSI-T2). The cases of Hom-HSI-T2 were generally associated with capsular enhancement, and were usually cystic tumors with high vascularities and mainly Antoni A tissues. On the contrary, the cases of Het-HSI-T2 were generally associated with homogeneous enhancement, and were usually solid tumors with low vascularities and various tissue components.
我们回顾性研究了21例经组织学证实的听神经鞘瘤，重点关注其磁共振成像（MRI）表现与组织学特征的相关性。所有病例在T1加权MRI上均表现为低信号强度。在T2加权MRI上，其中9例为均匀高信号强度（Hom-HSI-T2），12例为不均匀高信号强度（Het-HSI-T2）。Hom-HSI-T2病例通常伴有包膜强化，通常为高血管性的囊性肿瘤，主要由Antoni A组织构成。相反，Het-HSI-T2病例通常伴有均匀强化，通常为低血管性的实性肿瘤，具有多种组织成分。
