"PET-CT"
"Sinonasal malignancies consist of a variety of tumours, including carcinomas, sarcomas and a variety of other entities. They share similarities in how they present clinically; in many instances, distinguishing between them based on imaging is impossible."
"As these tumours enlarge and invade through bone into adjacent compartments, additional signs and symptoms will become evident depending on the location. They include visual symptoms or proptosis with orbital invasion, CSF rhinorrhoea, cranial nerve deficits or neurological symptoms due to invasion of the base of skull or intracranial compartment, and difficulty breathing, chewing or swallowing when growth is posteroinferior into the oral cavity or oropharynx 7. Tumours may grow forward and present as facial swellings 7."
"ovoid, polypoid or irregular mass"
