Aspergillosis presenting as a corticosteroid-responsive optic neuropathy.

Area of Science:

• Ophthalmology
• Infectious Diseases
• Radiology

Background:

• Orbital infections can present with varied symptoms, sometimes mimicking other conditions.
• Systemic corticosteroids, while treating inflammation, can predispose patients to opportunistic infections.

Observation:

• A case of orbital aspergillosis presented mimicking optic neuropathy.
• The patient's condition appeared to respond to steroid treatment initially.
• Serial CT scans and necropsy revealed an invasive fungal infection.

Findings:

• Orbital aspergillosis demonstrated aggressive behavior in the context of systemic corticosteroid use.
• The infection's invasive nature was confirmed through advanced imaging and post-mortem examination.
• Aspergillosis can present as a steroid-responsive optic neuropathy.

Implications:

• Clinicians should consider fungal infections like aspergillosis in the differential diagnosis of optic neuropathies, particularly in immunocompromised or steroid-treated patients.
• Early recognition and appropriate antifungal treatment are crucial for managing orbital aspergillosis.
• This case highlights the importance of considering opportunistic infections when evaluating steroid-responsive neurological deficits.
