COVID-associated aspergillosis (CAPA), and (COVID-19-associated mucormycosis) CAMCR cases are well registered. Physicians are suspicious about (COVID-19-associated mucormycosis) CAMCR especially if rhino-orbital or rhino-cerebral presentations are noted in severely ill patient with COVID-19 and Diabetes Mellitus.DM (Diabetes Mellitus) patients with COVID-19 develops Craniofacial pain without bump.
