Isolated cerebral phycomycosis presenting as focal encephalitis

Area of Science:

• Neurology
• Mycology
• Infectious Diseases

Background:

• Fungal infections of the central nervous system are uncommon, particularly in immunocompetent individuals.
• Phycomycosis, a group of fungal infections caused by Mucormycetes, typically affects individuals with specific risk factors like diabetes or immunosuppression.

Observation:

• A patient presented with clinical and radiological signs suggestive of focal encephalitis.
• No identifiable risk factors for phycomycosis were present in the patient's history.

Findings:

• Brain biopsy confirmed the presence of isolated cerebral phycomycosis.
• The causative fungal agent was identified as a species within the Mucorales order.

Implications:

• This case highlights the importance of considering rare fungal infections like cerebral phycomycosis in the differential diagnosis of focal encephalitis, even in the absence of typical risk factors.
• Early diagnosis through invasive procedures like brain biopsy is crucial for timely and appropriate management of CNS fungal infections.
