Summary

Central nervous system (CNS) mucormycosis is a rare fungal infection. Intravenous drug use is a key risk factor, and amphotericin B treatment improves survival rates for this dangerous brain infection.

Background:

Isolated central nervous system (CNS) mucormycosis is a rare and frequently fatal infection.
Prompt diagnosis and treatment are crucial for patient survival.

Observation:

A case of bilateral frontal lobe mucormycosis in a previously healthy woman is presented.
Intravenous drug use was identified as the most probable route of infection.
The patient survived after surgical drainage and amphotericin B treatment but experienced permanent neurological deficits.

Findings:

A review of 29 previous cases revealed that patients with isolated CNS mucormycosis are typically young males.
Intravenous drug use is the most significant risk factor, present in 67% of cases.
Amphotericin B treatment was the sole predictor of survival, decreasing mortality from 92% to 41%.

Implications:

Isolated CNS mucormycosis should be included in the differential diagnosis for brain abscesses, particularly in intravenous drug users.
Early administration of amphotericin B is critical and can be life-saving.
This highlights the importance of considering opportunistic infections in specific patient populations.
