Mycotic aneurysms as a rare cause of subarachnoid hemorrhage.

ABSTRACT: Aneurysmal subarachnoid hemorrhage (aSAH) caused by mycotic intracranial aneurysms (MIAs) is a rare cerebrovascular condition resulting from bacterial infiltration and arterial wall damage due to systemic or local infections. Due to limited data - often restricted to case reports or small series - no standardized diagnostic or therapeutic strategies exist. Therefore, this study aimed to characterize clinical, radiological, microbiological, and histopathological features of aSAH due to MIAs and to analyze treatment approaches in a larger cohort. We conducted a retrospective analysis of consecutive patients with aSAH from MIAs treated at two neurovascular centers between 2007 and 2024. Inclusion required both suggestive aneurysm morphology (e.g., distal, dysplastic) and evidence of systemic
