Isolated central nervous system aspergillosis in the acquired immunodeficiency syndrome.

Aspergillus infection involving the central nervous system are unusual, but should be included in the differential diagnosis in patients with the acquired immunodeficiency syndrome and neurologic signs and symptoms. Of the few reported AIDS cases with central nervous system aspergillosis, the majority have had focal brain abscesses. We report an atypical case that presented as a basal meningitis with pontine infarction secondary to invasive Aspergillus sinusitis.
