Abstract
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.
摘要
中枢神经系统原发性血管炎的组织病理学特征为缺血性病变和小瘀点出血。与CT或传统磁共振成像不同，梯度回波磁共振成像可显示这些慢性瘀点出血。我们在此报告一例经活检证实的42岁男性中枢神经系统原发性血管炎病例；梯度回波磁共振成像显示其皮质-皮质下脑区有多处瘀点出血。通过梯度回波磁共振成像识别瘀点出血有望成为支持中枢神经系统原发性血管炎诊断的有价值替代标志物。
