| 摘 要： | 目的：探讨周围神经鞘瘤的CT和MRI表现。方法：回顾性分析13例经病理证实的周围神经鞘瘤的CT和MRI表现，其中发生在颈椎和胸椎椎间孔内的2例、颈部1例、枕部1例、纵隔1例、胸壁1例及下肢7例。结果：肿瘤均呈椭圆形，边界清楚光滑，沿神经走行方向生长，2例有邻近椎间孔扩大。CT显示肿瘤包膜密度高，包膜内肿瘤组织密度低于肌肉组织。MRI T1WI显示肿瘤呈中～低信号，T2WI呈不均匀高信号，增强后有不均匀强化。其中显示靶征4例，神经出入征3例，脂肪包绕征8例，脂肪尾征7例及脑脊液尾征1例。结论：周围神经鞘瘤的影像学表现有一定特征性，CT和MRI对诊断有重要价值。

| Abstract: | Objective:To analyze the CT and MRI features of peripheral neurilemoma.Methods:The CT and MRI features of 13 patients with histopathology proved peripheral neurilemoma were retrospectively analyzed.The location of the tumor was cervico-thoracic intervertebral foramen(2 cases),neck,occipital region,mediastinum,chest wall for 1 case each,and lower limb(7 cases).Results:All of the tumors were oval shaped,well-defined and with the extent along the nerve distribution.Enlargement of intervertebral foramen could b... |
