Cerebral microbleeds (MB) and superficial siderosis (SS) are frequent neuroimaging findings in patients with logopenic progressive aphasia (LPA), often with frontal lobe predilection. Cerebral amyloid angiopathy (CAA) is hypothesized to be the major pathologic determinant of MB/SS in these patients; however, neuroimaging‐pathologic data are limited.

淀粉样血管病与 logopenic 进行性失语症微出血的关联：一项影像病理学研究

脑微出血 (MB) 和浅表铁沉积症 (SS) 是 logopenic 进行性失语 (LPA) 患者的常见神经影像学表现，通常伴有额叶倾向。脑淀粉样血管病 (CAA) 被假设为这些患者 MB/SS 的主要病理决定因素；然而，神经影像学病理数据有限。
