Rhinonasal mucormycosis is an aggressive fungal infection that primarily affects immunocompromised patients, particularly those with uncontrolled diabetes or post-COVID-19 complications. The infection begins in the nasal cavity and paranasal sinuses but may extend into the orbit and intracranial structures, resulting in severe complications such as blindness, stroke, and death.

Ultimate learning objective is:

• Recognizing the characteristic imaging features of rhino-nasal mucormycosis across various stages of disease progression.
• Identifying critical MRI findings indicative of orbital and intracranial extension, including early signs of vascular involvement, soft tissue infiltration, and neural invasion.
• Emphasizing the significance of MRI in guiding surgical planning and assessing post-treatment response.
• Highlighting the imaging features of  MRI in detecting disease extent, particularly in early stages, and discussing potential complementary imaging techniques.
