Mucormycosis infection is a rare but life-threatening opportunistic fungal infection caused by fungi of the order Mucorales. It predominantly affects immunocompromised individuals, including those with diabetes mellitus, haematological malignancies, or those having organ transplants or on long-term corticosteroid therapy.

Rhinocerebral mucormycosis is one of the most common forms, beginning in the nasal sinuses and spreading to the orbits, brain, and beyond through angioinvasion. The disease can progress rapidly, leading to vascular thrombosis, tissue necrosis, and systemic dissemination, making early diagnosis and intervention critical.
