A 65-year-old male patient presented with right facial pain and swelling of 10 days duration after 15 days of COVID-19 infection with poor diabetic control. A Axial CT image shows mucosal thickening involving the right maxillary sinus (white asterisk) with soft tissue infiltration and gas bubbles in the right anterior periantral fat (arrow) and the posterior periantral fat (red arrowhead). B Axial image in the patient shows right nasal cavity mucosal thickening (blue asterisk). Soft tissue infiltration through the right sphenopalatine foramen and pterygopalatine fossa (yellow arrow) is seen, as well as involvement of the right posterior periantral fat (red arrowheads). C Axial CT illustrates orbital involvement of with infiltration of the right medial and inferior extraconal orbital fat (blue arrows). D Axial CT shows a surgically proved subtle ulceration along the left side of the nasal septum (orange arrow). E Coronal CT confirms orbital fat involvement. F endoscopic view shows marked gangrene and necrosis of right nasal cavity, nasal septum, middle and inferior turbinate. Sinus surgical exploration revealed severely involved right nasal cavity and maxillary sinus, fungal culture revealed Mucor infection, patient survived after proper diabetic control and IV amphotericin B administration
