Abstract:
The authors describe a case of cerebral phaeohyphomycosis with lethal outcome within five weeks from surgical resection. The lesion consisted of a multilocular abscess in the left parietal lobe. The histopathologic findings showed a granulomatous reaction surrounding the abscess cavities. The causative fungus was clearly visible because of its brown-pigmented, septate, branched hyphae and spherical thick-walled cells, sometimes inside the multinucleated giant cells. Although no cultures were obtained from the exsudate, the possible diagnosis of cerebral cladosporiosis is discussed.
Insights
This case study details a fatal cerebral phaeohyphomycosis infection, rapidly progressing within weeks of surgery. The fungal elements observed suggest Cladosporium as a potential cause of this rare brain infection.
Area of Science:
- Mycology
- Neuropathology
- Infectious Diseases
Background:
- Cerebral phaeohyphomycosis is a rare and often fatal fungal infection of the brain.
- Fungal infections of the central nervous system can present with varied clinical and radiological findings.
Observation:
- A multilocular abscess in the left parietal lobe was identified in a patient.
- Histopathology revealed a granulomatous reaction surrounding abscess cavities.
- Microscopic examination showed brown-pigmented, septate, branched hyphae and spherical thick-walled fungal cells, some within multinucleated giant cells.
Findings:
- The characteristic fungal morphology pointed towards a diagnosis of phaeohyphomycosis.
- Despite the absence of cultures, the observed features suggested Cladosporium as the probable causative agent of cerebral cladosporiosis.
- The infection led to a lethal outcome within five weeks of surgical resection.
Implications:
- This case highlights the aggressive nature and rapid progression of cerebral phaeohyphomycosis.
- Accurate and timely diagnosis is crucial for managing rare fungal brain infections.
- Further research into the pathogenesis and treatment of cerebral phaeohyphomycosis is warranted.
