脑内非特异性炎性肉芽肿的影像诊断

The Imaging Diagnosis of Intracerebral Nonspecific Inflammatory Granuloma

目的探讨脑内非特异性炎性肉芽肿的影像特点。资料与方法回顾性分析10例经临床和手术病理证实的脑内非特异性炎性肉芽肿的临床和影像资料,着重分析其CT和MRI表现。结果10例患者中9例病灶均靠硬脑膜面,位于皮层或皮层下,10例病灶均见有明显强化,8例呈实性伴或不伴环形强化,7例可见局部脑膜强化。结论脑内非特异性炎性肉芽肿病灶多位于皮层或皮层下,增强后呈不规则实性伴或不伴环形强化,可见相邻脑膜局限性强化,这些影像特征有助于本病的鉴别诊断。

Objective To investigate the imaging features of the intracerebral nonspecific inflammatory granuloma. Materials and Methods The CT and MRI features of 10 cases with intracerebral nonspecific inflammatory granuloma con- firmed by clinical information and surgical pathology were analyzed retrospectively. Result In 9 of 10 cases,the lesions mainly located in cortex or subcortex region near to dura , all lesion showed markedly enhancement. In 8 cases , the enhanced lesions represented fulfill-like with or without ring-like shape. 7 cases showed local meningeal enhancement. Conclusion Intracerebral nonspecific inflammatory granuloma mainly located in cortex or subcortex region, which is presented with fulfill-like with or without ring-like and local meningeal enhancement.
