ROLE OF DIAGNOSTIC IMAGING TO MALIGNANT SINUS TUMORS IN PRESURGICAL STAGING

Abstract

The aim of this study is to describe the current role of ima-

paranasali

ging in pre-surgical planning, reporting 25 cases of para-

nasal sinus tumors examined in our Institute. Between Ju-

ne 2006 and May 2008, we identified 25 patients with ma-

lignant tumors of the paranasal sinuses. All of the patients

were evaluated with CT and/or MR exams. US were used

to assess regional lymph node involvement. When neces-

sary CT-PET scanning using FDG, was done. Diagnostic

imaging is essential during the initial work-up of a patient

suspected of having a paranasal sinus tumor. The role of

imaging is to define the tumor extension, nodal involve-

ment, metastases and recurrences in the postoperative

patient. CT and MR imaging are the primary modalities

employed; each have advantages and disadvantages but

tend to be complementary
