CT of the head-
The right nasal cavity is occupied by a contrast enhancing soft tissue mass which causes multifocal aggressive osteolysis of the nasal turbinates, nasal, vomer, maxillary, and palatinal bone as well as lysis of the bony orbita and nasal septum. The mass penetrates into the right retrobulbar space and left nasal cavity as well as towards the dorsum of the nose. The cribriform plate is intact. The dependent portion of the right frontal sinus contains a moderate amount of fluid with a horizontal fluid level. The right submandibular lymph nodes present moderate symmetric enlargement with a regular contrast enhancement pattern. The medial retropharyngeal lymph nodes are within normal limits.
