Rhino-orbital-cerebral mucormycosis

Area of Science:

• Mycology
• Infectious Diseases
• Ophthalmology

Background:

• Mucormycosis, specifically rhino-orbital-cerebral mucormycosis (ROCM), is a life-threatening fungal infection.
• Commonly affects immunocompromised individuals with conditions like diabetes mellitus and hematological malignancies.
• Pathogenesis involves angioinvasion, thrombosis, and tissue necrosis, often originating in the sinuses.

Purpose of the Study:

• To review the clinical features, pathogenesis, and management of ROCM.
• To emphasize the importance of early diagnosis and comprehensive treatment strategies.
• To highlight the need for improved diagnostic and therapeutic modalities.

Main Methods:

• Literature review focusing on sinus, sino-orbital, and rhinocerebral infections caused by Mucorales.
• Analysis of underlying conditions, risk factors, and pathophysiological mechanisms.
• Discussion of clinical manifestations, diagnostic challenges, and therapeutic approaches.

Main Results:

• ROCM can rapidly progress from sinus involvement to orbital and cerebral structures.
• Early signs may include diplopia and ophthalmoplegia, even with negative imaging.
• Maxillary sinus mucormycosis presents distinct features, including hard palate ulceration.
• Orbital apex syndrome is a severe complication threatening vision and cranial nerves.

Conclusions:

• Prompt diagnosis and multidisciplinary management are critical for improving ROCM outcomes.
• Treatment involves antifungal therapy (e.g., amphotericin B), addressing predisposing conditions, and surgical debridement.
• Further research is needed for enhanced early diagnosis and novel therapeutic interventions.
