Polymicrobial brain abscess in a homosexual man with Kaposi's sarcoma

|February 1, 1984
Summary
A brain abscess in an individual with acquired immunodeficiency syndrome (AIDS) was caused by multiple pathogens, including Toxoplasma gondii and Candida. Treatment improved fever and overall health, but vision loss persisted.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Acquired immunodeficiency syndrome (AIDS) increases susceptibility to opportunistic infections affecting the central nervous system.
- Kaposi's sarcoma is a common AIDS-defining illness that can be associated with opportunistic infections.
Observation:
- A 39-year-old homosexual male with AIDS and Kaposi's sarcoma presented with fever and progressive visual field defects.
- Brain imaging revealed a left parieto-occipital abscess.
Findings:
- Surgical excision of the abscess yielded organisms consistent with Toxoplasma gondii and Candida species.
- Staphylococcus epidermidis was identified in cultures from the abscess.
- The patient received appropriate antimicrobial therapy for the polymicrobial infection.
Implications:
- The polymicrobial nature of the brain abscess highlights the diverse opportunistic infections that can occur in individuals with advanced HIV.
- While systemic symptoms resolved, the visual field defect remained, indicating potential for irreversible neurological damage.
- This case underscores the importance of prompt diagnosis and broad-spectrum antimicrobial treatment for central nervous system infections in immunocompromised patients.
