MR Imaging Findings of Orbitofacial Infarction Secondary to Rhinoorbital Mucormycosis: A Case Report

ABSTRACT

Rhino-orbital mucormycosis is the most frequently fatal fungal infection commonly occurring in patients with poorly controlled diabetes mellitus and and those who are immunocompromised, and requires prompt treatment. We describe a case of rhino-or-bital mucormycosis with orbital cellulitis and paranasal sinusitis, as seen on initial MR images, which on follow-up images had evol ved to orbitofacial infarction. MR imaging was useful for the demonstration of orbitofacial infarction, seen as areas of lack of enhancement and thus suggesting vascular invo l vement by mucor hyphae.
