Early diagnosis of mucormycosis is based on clinical, radiographic, and histopathological findings. Radiographic diagnosis includes plain radiographs, orthopantomogram OPG, and cone-beam computed tomography CBCT view. Imaging technique includes computerized tomography of paranasal sinusCT PNS view with contrast and gadolinium-enhanced magnetic resonance imaging MRI. Mucorales are rapid growers (3-7 days) therefore culture is essential for the diagnosis of mucormycosis since it allows identification at genus and species levels. Nasal scrapings/deep nasal swab /pus swab is collected for KOH (potassium hydroxide) mount/ culture and biopsy is collected from denuded/necrosed bone. Histopathologically mucormycosis is confirmed by Hematoxylin and eosin stain, Periodic acid-schiff PAS stain, and Grocott gomori methamine silver stain. However, negative culture reports are often seen despite ofpositive histological findings. ].
