A COMPARISON OF THE CORELATION OF CT SCAN AND MM FINDINGS WITH TISSUE PATHOLOGY IN THE BENIGN AND MALIGNANT NASAL MASSES

1% of the total neoplasic lesion are located in the nasal cavity and sinuses and 1000 new cases are discovered in USA every year. Neoplasms in the nasal cavity and sinuses involve males and females In the ratio 2:1 and the highest rate of incidence is between the 5th and 7 th decades. Importance of early diagnosis and extension of disease is clearly known. In our study, 12 Patients (9 males and 3 females , between 43 to 65 years old) who referred to the CT Scan center of Sayyed Al,. Shohada Hospital were examined by CT scan and MR1 with and without contrast media and then the CT and MRI reports were corelated with tissue pathology reports . Size of the mass has a direct relationship with malignancy . Bone destruction was better visualized by CT while real size of the mass and soft tissue invasion was differentieted by MR1 . In our :study accuracy rite was 88% for CT Scan and 98% for MRI , but further evaluation for better and more reliable fesults is recommended.
