Magnetic resonance (MR) images of 16 peripheral nerve tumors (14 patients) were correlated with histopathologic appearance. Thirteen patients had surgically proved neuro-fibromatosis. There were 10 neurofibromas, four schwannomas, and two neurofibrosarcomas. Seven of the 10 neurofibromas showed a target pattern of increased peripheral signal intensity and decreased central signal intensity on T2-weighted images. This pattern appeared to correspond to a distinctive zonal histologic appearance that was found only in the neurofibromas. This pattern was not seen on MR images of the other peripheral tumors.
对16例周围神经肿瘤(14例患者)的磁共振(MR)图像与组织病理学表现进行了对比。13例患者经手术证实患有神经纤维瘤病。其中有10例神经纤维瘤、4例施万细胞瘤和2例神经纤维肉瘤。10例神经纤维瘤中的7例在T2加权图像上表现为外周信号强度增加、中心信号强度降低的靶征。这种表现似乎与仅在神经纤维瘤中发现的一种独特的分层组织病理学表现相对应。在其他周围肿瘤的MR图像上未见到这种表现。
