When faced with expanding brain lesions of unknown origin showing a ring-shaped enhancement on post-contrast imaging, we use definite criteria to direct further investigation and distinguish among a number of possible diagnostic hypotheses. However, a correct diagnosis may be difficult in some cases, especially when dealing with less frequent conditions. This is the case of actinomycosis, a highly treatable but insidious infection for which nowadays there may be a low level of attention. Brain localization is associated with a significant morbidity and may represent a true diagnostic pitfall. Here we report the difficulties encountered with a case of central nervous system actinomycosis.
当面对起源不明的脑内病变，其在增强后影像上显示出环形增强时，我们会使用明确的标准来指导进一步的检查，并区分出许多可能的诊断假设。然而，在某些情况下，正确的诊断可能会很困难，尤其是在处理不太常见的情况时。放线菌病就是这种情况，这是一种高度可治疗但隐匿的感染，现在可能关注度较低。脑内定位与较高的发病率相关，并且可能是一个真正的诊断陷阱。在此，我们报告了一例中枢神经系统放线菌病所遇到的困难。
