A 77-year-old man, with no trauma history, presented with recurrent transient left arm paresthesia for 2 weeks. Brain MRI showed acute cortical subarachnoid hemorrhage and criteria for probable cerebral amyloid angiopathy (CAA) (figure, video 1). A 24-hour video-EEG recorded 4 transient focal neurologic episodes (TFNE) with the following sequence: paresthesia always starting from the hand and slowly spreading to the arm, the shoulder, and sometimes the perioral area. During these episodes, EEG remains unchanged.
