CT of the skull-

The right nasal cavity and frontal sinus are filled by a mildly heterogeneous soft tissue attenuating and irregularly contrast enhancing mass. Multifocal amorphous mineral attenuating areas are noted within the mass. The mass perforates into the left nasal cavity and there is complete obstruction of the ventral and middle nasal meatus on the left side. The nasal septum presents lysis and moderate deviation to the left side. Complete destruction of the conchal and turbinate structures is seen in the right nasal cavity associated with the mass. Partial destruction is noted in the left nasal cavity. The pars orbitalis of the frontal bone presents regional permeative osteolysis.  One of the right submandibular lymph nodes on the right side is markedly enlarged and rounded.
