[Focal brain lesion due to cerebral aspergillosis in a patient with AIDS. Case report and literature review].

Cerebral aspergillosis is a rare disease with high mortality rates in AIDS patients. It is important to take this into account in the differential diagnosis of a brain expansive lesion. A high level of suspicion is required to make an early diagnosis. We present a case of an HIV-infected patient with progresive neurological disease caused by Aspergillus flavi. We review 40 previously published cases of central nervous system aspergillosis in patients with AIDS.
