A 74-year-old woman was admitted to our hospital with a history of episodes of left-sided hemiparesis and numbness for few minutes. A brain MRI showed cortical subarachnoid blood and diffuse cortical microbleeds, compatible with a diagnosis of cerebral amyloid angiopathy, according to modified Boston criteria[1]. Other possible causes of the MRI findings, such as coagulopathy and traumatic brain injury, were excluded.

Cerebral amyloid angiopathy, a common cause of lobar hemorrhage in older patients, can also present with transient focal neurological episodes, which are sometimes known as ‘amyloid spells’. These are stereotyped, recurrent, transient episodes of numbness or weakness and may mimic a transient ischemic attack[1],[2],[3],[4],[5].
