Intracranial Nocardia in the setting of AIDS.

Nocardia intracranial abscesses occur almost exclusively in patients who are immunocompromised due to diabetes, transplantation, or HIV/AIDS. Patients usually present with seizures, headaches, fevers, and menin-gismus. Laboratory evaluation is nonspecific but may reveal an elevated erythrocyte sedimentation rate and white blood cell count. An important task in the workup of intracranial infection is searching for local causes such as sinusitis, otitis media, or mastoiditis.
