Inflammation in Cerebral Amyloid Angiopathy-Related Transient Focal Neurological Episodes.
Transient focal neurological episodes (TFNE), often associated with convexity subarachnoid hemorrhage (cSAH), are common in cerebral amyloid angiopathy (CAA), but their pathophysiology remains incompletely understood. In six patients with unremitting TFNE, using high-resolution post-contrast magnetic resonance imaging and vessel wall imaging (VWI), we found various combinations of transient leptomeningeal, parenchymal and vessel wall enhancement; in 5 of 6 the enhancement included regions corresponding anatomically to symptoms. Three patients had resolution of TFNE and enhancement (2 with corticosteroid treatment, 1 without). Our observations suggest that inflammation might contribute to the pathophysiology of CAA-related TFNE and cSAH, with potential wider relevance for the associated high risks of recurrent ICH in CAA more generally.

期刊介绍：
Annals of Neurology publishes original articles with potential for high impact in understanding the pathogenesis, clinical and laboratory features, diagnosis, treatment, outcomes and science underlying diseases of the human nervous system. Articles should ideally be of broad interest to the academic neurological community rather than solely to subspecialists in a particular field. Studies involving experimental model system, including those in cell and organ cultures and animals, of direct translational relevance to the understanding of neurological disease are also encouraged.
