Aspergillus infection causing cerebral aneurysm

Background: Aspergillosis infection of the central nervous system (CNS) is a rare disease and corticosteroid use has increased the number of cases. It presents a high lethality rate and has to be aggressively treated. Methods: A review of literature was done and 38 cases were identified involving cerebral aneurysms caused by this fungus to date. Conclusion: Aspergillus infection is very rare worldwide but its frequency is currently in expansion because immunocompetence failure is growing up: it has no specific presentation, making diagnosis difficult. Its prognosis is poor, so the disease has to betreated as early as posible.
