Maxillary mucormycosis and concurrent osteomyelitis in a post-COVID-19 patient with new onset diabetes mellitus.

The occurrence of invasive fungal respiratory superinfections in patients with COVID-19 has gained much attention in the post-COVID era. The elucidation of invasive fungal sinusitis with osteomyelitis as a rare aggressive infection that requires prompt diagnosis and treatment to prevent fatal consequences has been noteworthy. Cone-beam computed tomography findings in those patients are central to early diagnosis and management. Here we report a case of post-COVID mucormycosis with osteomyelitis of the maxilla in a 72-year-old woman with a history of recently diagnosed diabetes mellitus.
