Background: Mucormycosis is an angio-invasive fungal infection due to fungi of the order Mucorales. This is known to occur in patients with uncontrolled diabetes, post transplant and cancer. Most individuals are exposed to these fungi on a daily basis, but people with weakened immune systems are more susceptible to infection. The infection begins in the nose and para nasal sinuses due to inhalation of fungal spores. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. Early diagnosis and prompt treatment can reduce the mortality and morbidity of this lethal fungal infection.
