Case report

Restricted access

✓ Intracranial aneurysms are an uncommon manifestation of fungal infection. A case is described in which the formation of an aneurysm followed an intracranial intraoperative Aspergillus infection attributable to a long period of preoperative antibiotic medication and immunosuppressive therapy with steroids.
