This is a case report of a 46-year-old female with undiagnosed diabetes, COVID-19, and mucormycosis. Mucormycosis is a rare, rapidly progressive disease process characterized by an insidious onset of vague symptoms and is associated with a high mortality rate. The patient initially presented at two outside ophthalmology clinics due to right eye pain and was prescribed steroids. Upon presentation to our institution's Emergency Department, the patient's pain had significantly increased along with new symptoms of ptosis and failure to adduct the right eye. Laboratory results demonstrated leukocytosis, hyperglycemia, and a positive SARS-CoV-2 test. Magnetic resonance imaging confirmed a diagnosis of mucormycosis and the patient underwent surgery and began intravenous antifungal therapy. This discussion addresses the presenting features of mucormycosis in the emergency department while highlighting the need for immediate investigation due to the fungi's rapidly progressive nature.
