A patient with surgical and neuropathologically confirmed subdural sarcoid granuloma was evaluated using angiography, contrast-enhanced CT and MR. MR images were obtained on a superconducting magnet with T1, intermediate and multi-echo T2 weighted sequences. Review of the 2 prior cases of subdural sarcoid granuloma from the literature evaluated with MR confirm the variable nature of signal intensities of the lesion. MR was most useful in anatomically evaluating the lesion and planning neurosurgical intervention but both CT and MR alone, in this case, did not definitely obviate the other differential diagnosis including meningioma en-plaque, lymphoma, or metastasis.
一名经手术和神经病理学确诊为硬膜下结节病肉芽肿的患者接受了血管造影、增强CT和磁共振成像（MR）检查。MR图像是在超导磁体上采用T1加权、中间加权和多回波T2加权序列获得的。回顾文献中另外2例经MR评估的硬膜下结节病肉芽肿病例，证实了病变信号强度的多变性。MR在对病变进行解剖学评估和规划神经外科干预方面最有用，但在本例中，单独的CT和MR都不能明确排除其他鉴别诊断，包括斑块状脑膜瘤、淋巴瘤或转移瘤。
