Mucormycosis is a fatal angio-invasive fungal infection associated with a high mortality. Apart from the traditional risk factors, COVID-19 infection and steroid therapy for the same have been recently identified to predispose to this life-threatening infection. Usual presentations of mucormycosis include rhino-orbito-cerebral, pulmonary, gastrointestinal, renal and cutaneous involvement. We report an unusual case of mediastinal involvement by mucormycosis in a patient recovering from moderate COVID-19 pneumonia. Early diagnosis, prompt initiation of antifungal therapy accompanied by timely surgical debridement were pivotal in averting morbidity and mortality in this patient.
