Summary
This case report describes a rare extra-axial fungal granuloma caused by Blastomyces dermatitidis. The fungal lesion mimicked a meningioma on imaging and during surgery.
Area of Science:
- Neurology
- Mycology
- Pathology
Background:
- Extra-axial lesions in the clival region pose diagnostic challenges.
- Fungal infections, particularly Blastomyces dermatitidis, are uncommon causes of central nervous system masses.
Observation:
- A case of an extra-axial lesion in the lower clivus is presented.
- Radiological imaging suggested a meningioma.
- Macroscopic appearance during surgery was also consistent with a meningioma.
Findings:
- Histopathological examination confirmed the lesion to be a fungal granuloma caused by Blastomyces dermatitidis.
- The fungal granuloma successfully simulated a meningioma.
Implications:
- This case highlights the importance of considering fungal infections in the differential diagnosis of extra-axial clival masses.
- Accurate preoperative diagnosis is crucial for appropriate treatment and patient management.
