Due to the angioinvasive nature of the disease, it is rapidly progressive and can be lethal if not managed expeditiously. In patients with underlying conditions of immunosuppression, diabetes mellitus, transplantation, COVID-19, intravenous drug and substance use and pyelonephritis, which is unable to be controlled via regular antibiotics, mucormycosis must be considered on the differential and antifungals must be empirically started. Most cases are often diagnosed on histopathology, which causes delayed treatment and resolution. We present a case of emphysematous pyelonephritis diagnosed on imaging and was later found to have mucormycosis on histopathological examination. ER -
