Four cases of pathologically proven benign schwannoma were reviewed and the histology was compared with the CT appearance. Each tumor was of mixed CT attenuation, which has been thought to be an indication of malignancy. The areas of inhomogeneity on CT in these cases may relate pathologically to confluent areas of hypocellularity adjacent to densely cellular or collagenous regions, xanthomatous change, and/or regions of cystic degeneration. It is concluded that schwannomas may have areas of mixed attenuation on CT, that these areas can probably be explained by distinct findings on pathologic examination, and that inhomogeneity can represent benign or malignant disease.
回顾了4例经病理证实的良性神经鞘瘤，并将其组织学与CT表现进行了比较。每个肿瘤的CT密度均为混合性，而这种情况曾被认为是恶性的指征。这些病例中CT上的不均匀区域在病理上可能与紧邻细胞密集或胶原区域的细胞减少融合区、黄色瘤样改变和/或囊性变区域有关。得出的结论是，神经鞘瘤在CT上可能有混合密度区域，这些区域可能可以通过病理检查的不同发现来解释，并且不均匀性可代表良性或恶性疾病。
