High resolution CT was found to be an extremely useful and sensitive method for evaluation and diagnosis of lesions involving the optic nerve sheath complex. Segmental "tram tracking" associated with fusiform or focal eccentric nerve sheath enlargement was confirmed to be of neoplastic origin in all cases, whereas "tram tracking" and tubular nerve sheath thickening included tumorous and a great variety of non-tumorous lesions as well.
高分辨率CT被发现是评估和诊断累及视神经鞘复合体病变的一种极其有用且敏感的方法。在所有病例中,与梭形或局灶性偏心性神经鞘增大相关的节段性“轨道征”被证实为肿瘤性起源,而“轨道征”和管状神经鞘增厚既包括肿瘤性病变,也包括各种各样的非肿瘤性病变。
