脑微出血与不常见疾病相关性的研究进展

Advances in the study of correlation between cerebral microbleeds and uncommon diseases

脑微出血属于脑小血管疾病。脑微出血由含铁血黄素组成,是顺磁性的,并且可由磁共振磁敏感序列检测。脑微出血在脑卒中和脑变性病方面越来越受到重视。但有些少见疾病也伴有脑微出血的发生,不同疾病中脑微出血的数量、分布、大小各不相同。了解脑微出血不常见的病因不仅有助于这些不常见病的诊断及预后,而且有助于更好地了解脑微出血发展的不同病理生理。本文主要阐述脑微出血与少见病的关系。

Cerebral microbleeds(CMBs)are one kind of neuroimaging manifestations in cerebral small vessel disease,pathologically correlated with hemosiderin deposition.Susceptibility-weighted imaging can be used to assess CMBs.CMBs are increasingly recognized in the fields of cerebrovascular diseases and neurodegenerative diseases.However,some of rare diseases can also manifest CMBs.It is therefore necessary to reliably evaluate their presence and distribution in the brain.Understanding the uncommon causes of CMBs is not only helpful in diagnosis and prognosis of these rare diseases,but can also help in better understanding different pathophysiology involved in the development of CMBs.In this article,we described uncommon causes of CMBs.
