Cerebral microangiopathy (CM) has become a common disease related to improved neuroimaging modalities and an increased life expectancy. Intracerebral tumor-like mass lesions have rarely been reported in cases of cerebral amyloid angiopathy (CAA) in elderly patients. However, tumor-like mass lesions from CM without amyloid deposits have rarely been reported. These two angiopathies may have different pathogeneses and neuroimaging characteristics. Herein, we present the case of an 83-year-old man with CM mimicking a high-grade glioma. We described the possible pathogenesis and different neuroimaging features of CM compared to CAA.
