中枢神经系统原发性血管炎的组织病理学特征是缺血性病变和小的点状出血。与CT或常规MR成像不同，梯度回波MR成像显示了这些慢性瘀点。我们在此报告一例经活检证实的原发性中枢神经系统血管炎的42岁男子，谁梯度回波磁共振成像显示多个点状出血在皮质-皮质下脑区。通过梯度回波磁共振成像识别点状出血有望成为支持CNS原发性血管炎诊断的有价值的替代标记物。
Primary angiitis of the CNS is histopathologically characterized by ischemic lesions and small petechial hemorrhages. Unlike CT or conventional MR imaging, gradient-echo MR imaging depicts these chronic petechial hemorrhages. We herein report the case of biopsy-proved primary angiitis of the CNS in a 42-year-old man; whom gradient-echo MR imaging revealed multiple petechial hemorrhages in the cortical-subcortical brain regions. The identification of petechial hemorrhages by gradient-echo MR imaging promises to be a valuable surrogate marker supporting the diagnosis of primary angiitis of the CNS.
