Infections of the nervous system caused by fungi of the genus aspergillus, most commonly aspergillus fumigatus. Aspergillus infections may occur in immunocompetent hosts, but are more prevalent in individuals with immunologic deficiency syndromes. The organism may spread to the nervous system from focal infections in the lung, mastoid region, sinuses, inner ear, bones, eyes, gastrointestinal tract, and heart. Sinus infections may be locally invasive and enter the intracranial compartment, producing meningitis, fungal; cranial neuropathies; and abscesses in the frontal lobes of the brain.
