Peripheral enhancement of intracranial lesions on CT examination is still being considered by some radiologists as specific for an abscess or a cystic tumor. A review of the last 4,000 scans at this institution has demonstrated that it is neither specific nor, in many cases, of much help in the differential diagnosis of the lesions. Examples of the various types of lesions that can demonstrate peripheral enhancement are shown. It is suggested that many if not all types of pathology would demonstrate this effect if the cranial CT scans were done at a fortuitous time or sequentially. Some differential diagnostic suggestions are also made.
一些放射科医生仍认为，颅内病变在CT检查时出现的周边强化对脓肿或囊性肿瘤具有特异性。对该机构最近4000份扫描结果的回顾表明，这种强化既不具有特异性，而且在许多情况下，对病变的鉴别诊断也没有太大帮助。文中展示了可出现周边强化的各类病变实例。研究表明，如果颅脑CT扫描是在偶然时间或按顺序进行，那么许多甚至所有类型的病变都会显示出这种强化效应。文中还给出了一些鉴别诊断建议。
