We report a case of intracranial foreign body granuloma that showed features of a high grade tumor on magnetic resonance (MR) imaging. However, the relative cerebral blood volume was not increased in the enhancing mass on perfusion MRI and the choline/creatine ratio only slightly increased on MR spectroscopy. The results suggest that the lesion is benign in nature. Perfusion MRI and MR spectroscopy may be helpful to differentiate a foreign body granuloma from a neoplastic condition.
我们报告了一例颅内异物性肉芽肿病例，该病例在磁共振成像（MR）上表现为高级别肿瘤的特征。然而，灌注 MRI 上增强肿块的相对脑血容量并未增加，磁共振波谱上的胆碱/肌酸比值也仅略有增加。结果表明，病变性质为良性。灌注 MRI 和磁共振波谱可能有助于将异物性肉芽肿与肿瘤性病变区分开来。
