IMAGING IN RHINOCEREBRAL MUCORMYCOSIS

Corona epidemic has brought many infections to the fore one of these
is mucormycosis. It is a fungal disease which occurs in patients with
underlying conditions such as diabetes, malignancies, patients who
have undergone organ transplantation and patients on long term steroid
administration are susceptible to mucormycosis. Infection commonly
occurs through inhalation of fungal spores from air. Mucormycosis is
not contagious, that is it does not spread from one person to another.
Recently, several patients have reported to hospital around the 3rd
week after onset of symptoms of COVID-19 with features suggestive
of sinonasal disease. It is suspected that the increase in number of cases
of mucormycosis in these patients is possibly due to misuse or overuse
of steroids that leads to uncontrolled hyperglycemia. Some clinicians
have suggested that use of industrial oxygen instead of medical
oxygen, unhygienic humidiers, prolonged ICU stay and unwarranted
administration of antibiotics may have predisposed the patients to
develop mucormycosis. The diagnosis and treatment is based on
imaging by CT Scan and MRI. Here we describe imaging ndings in
patients of rhinocerebral mucormycosis presenting to department of
Radiodiagnosis.
