We present a case of multifocal enhancing lesions confined to the right cerebral hemisphere that mimicked diffuse neoplasm. MR spectroscopy revealed not only minimal elevation of the choline peak, but also marked elevation of the glutamate and glutamine peaks, findings that are more suggestive of an inflammatory process. Biopsy showed lymphocytic vasculitis, a rare variant of primary angiitis of the CNS. Following appropriate medical therapy, MR imaging demonstrated complete resolution of the lesions.
我们报告一例局限于右侧大脑半球的多灶性强化病变,其表现类似弥漫性肿瘤。磁共振波谱不仅显示胆碱峰轻度升高,还显示谷氨酸和谷氨酰胺峰显著升高,这些表现更提示为炎症过程。活检显示为淋巴细胞性血管炎,这是中枢神经系统原发性血管炎的一种罕见变异型。经过适当的药物治疗后,磁共振成像显示病变完全消退。
