The objective of this study was to correlate enhanced CT images of noncalcified tuberculomas with histological findings, in order to search for characteristic CT enhancement patterns. Over 7 years, 12 noncalcified tuberculomas were surgically resected. Enhanced CT images of these tuberculomas were reviewed and correlated with histological studies. Ring or central-curvilinear enhancement was present in nine of 12 tuberculomas (75%). In those with ring or central-curvilinear enhancement, the low-density region was histologically confirmed to be caused by caseous or liquefied necrotic material, and a von Willebrand factor stain showed moderate to marked vascularity of the enhanced areas. Three tuberculomas showed nonspecific enhancement patterns. Histologically, each of these contained central caseous necrotic material, and two showed a poor vascularized peripheral fibrotic zone.
本研究的目的是将非钙化结核瘤的增强CT图像与组织学结果相关联，以寻找特征性的CT增强模式。在7年多的时间里，12例非钙化结核瘤接受了手术切除。对这些结核瘤的增强CT图像进行了回顾，并与组织学研究相关联。12例结核瘤中有9例（75%）出现环形或中心曲线状增强。在那些出现环形或中心曲线状增强的病例中，低密度区域经组织学证实是由干酪样或液化坏死物质引起的，血管性血友病因子染色显示增强区域有中度至明显的血管形成。3例结核瘤表现为非特异性增强模式。组织学上，每例均含有中心干酪样坏死物质，其中2例显示外周纤维化区域血管化不良。
