The CT appearances of 30 patients with a total of 58 intracranial tuberculomas are discussed. Of specific interest in this study is the relatively high incidence of patients who presented with the target sign. To date there has been only 1 report of 4 cases with this appearance on CT. Four basic patterns of post contrast enhancement are described. As suggested by Welchman this study concludes that the target sign is pathognomonic of an intracranial tuberculoma.
本文讨论了30例患者共58个颅内结核瘤的CT表现。本研究特别感兴趣的是出现靶征的患者比例相对较高。迄今为止,仅有1篇报告描述了4例CT表现为此征象的病例。本文描述了增强扫描后的四种基本强化模式。正如韦尔奇曼所指出的,本研究得出结论,靶征是颅内结核瘤的特征性表现。
