Cerebral Paecilomyces javanicus infection. An ultrastructural study.
Acta Neuropathologica
|January 1, 1986
Summary
A rare case of Paecilomyces javanicus endocarditis in a diabetic patient led to cerebral fungal embolism. This study details the rare cerebral manifestations and provides the first ultrastructural analysis of the fungus in infected tissue.
Area of Science:
- Medical Mycology
- Neurology
- Cardiology
Background:
- Endocarditis following prosthetic valve replacement poses significant risks.
- Cerebral complications of fungal infections are uncommon, particularly with non-Aspergillus species.
- Diabetes mellitus is a known risk factor for invasive fungal infections.
Observation:
- A 41-year-old diabetic woman presented with endocarditis caused by Paecilomyces javanicus six years after mitral valve replacement.
- The patient developed a cerebral fungal embolism, vasculitis, infarction, and hemorrhage.
- Paecilomyces javanicus was identified from brain tissue and aortic valve cultures.
Findings:
- This report documents the rare cerebral manifestations of Paecilomyces javanicus infection.
- The study provides the first ultrastructural description of Paecilomyces javanicus from infected human tissue.
- Ultrastructural analysis revealed characteristic fungal cell wall and membrane structures, along with novel findings in hyphal morphology.
Implications:
- This case highlights the potential for rare fungal pathogens to cause severe neurological complications in immunocompromised or device-bearing patients.
- Understanding the ultrastructure of Paecilomyces javanicus may aid in diagnosis and treatment strategies for invasive fungal infections.
- Further research into fungal embolism and vasculitis is warranted.
