SIMPLE AND CONTRASTED COMPUTED TOMOGRAPHY IN EPIDERMOID CARCINOMA OF THE TONGUE: INSTITUTO NACIONAL ONCOLOGÍA Y RADIOBIOLOGÍA

Abstract

Computed Tomography continues as the diagnostic technique of choice for initial staging and follow-up of tongue cancer patients. Objective: To determine the imaging characteristics by Simple and Contracted Computed Tomography to cases with epidermoid tongue carcinoma. Materials and methods: A preliminary, descriptive, prospective investigation was conducted in a sample of 21 cases. Results: The predominant age was between 60-65 years, with a history of smoking and/or alcoholism (63.4%). The largest number of cases had tumors at the base (n=11; 52.38%) and right edge (no=5; 23.81%) of the tongue, with submentonian ganglion sockets (n=9; 42.86%), submandibular (n=6; 28.57%) and middle jugular (n-4; 19.05%). All primary tumors (n=21; 100%) highlighted after the endovenous contrast, of which 19 (90.48%) showed an intense and homogeneous uptake pattern. Mostly no vascular infiltration was observed (n=20; 95.24%), nor infiltration of subcutaneous tissue (n=20; 95.24%) bone infiltration (no=8; 38.10%). Glandular infiltration and midline crossing were specified in 8 cases (38.10%) respectively. Conclusions: Cases with tongue tumors predominate in men over 60 years of age with risk factors such as smoking and/or alcoholism. Proven tomography makes it possible to redefine imaging indicators in tumor architecture and ganglion for the diagnosis of tongue cancer. It is recommended to include dynamic manoeuvre in the evaluation of dimensions, extent of primary injury and assessment of gum thickening as a predictor of future bone metastases.
