COVID-19-Associated Mucormycosis in a Tertiary Care Hospital in India: A Case Series

Mucormycosis is a disease that usually occurs in immunocompromised patients or those with uncontrolled diabetes mellitus. The second wave of the coronavirus disease 2019 (COVID-19) pandemic in India was accompanied by an unexpected rise in mucormycosis cases, ranging from the most commonly occurring Rhino-orbital-cerebral mucormycosis (ROCM) to rare cases of pulmonary and gastrointestinal mucormycosis. The majority of cases that presented to our hospital were individuals with underlying diabetes mellitus who received steroids for COVID-19 before being diagnosed with mucormycosis. In this case series, we present five rhino-orbital-cerebral mucormycosis cases that were histopathologically positive and treated at a tertiary-care hospital in India. Magnetic resonance imaging (MRI) of all of the patients demonstrated orbital apex syndrome and diffuse or focal infiltration of the cavernous sinus. Cases were treated with anti-fungal drugs, transcutaneous retrobulbar injection of amphotericin B (TRAM B), along with appropriate surgical excision and debridement of the involved tissue. The essential elements for successfully managing this fatal infection are control of the predisposing factors, early detection, anti-fungal drugs, and surgical debridement of the involved tissues.
