Mucormycosis is a rare life threatening invasive fungal infection caused by fungi of order mucorales commonly rhizopus. It usually occurs in immune compromised individuals like diabetic ketoacidosis, leukemia, lymphoma, severe malnutrition, high dose corticosteroids and organ transplantation. It occurs in many forms but the most common being rhinocerebral mucormycosis. A black necrotic eschar is the hallmark of mucormycosis. Patients present with varying manifestations like multiple cranial nerve palsies, unilateral periorbital facial pain, orbital inflammation, eyelid edema, blepharoptosis, proptosis, ophthalmoplegia, headache, and acute loss of vision. Here we describe an unusual presentation of a case of rhinocerebralmucormycosis in an adult female with diabetes mellitus. The reason to present this case is because of the unusual clinical presentation, course and how we arrived at the final diagnosis of mucormycosis.
