Abstract
Laryngeal cancer is the second most common cancer of the
respiratory system after lung cancer. The majority of the laryngeal tumors are
squamous cell carcinomas which arise from the mucosal surface and are
properly detected by endoscopic examination .However, clinical and
endoscopic examinations failed to detect the invasion of the laryngeal
skeleton as well as the extra laryngeal soft tissues, therefor many advanced
laryngeal tumors are clinically underestimated.
Imaging of laryngeal tumors is crucial for evaluation, preparing,
treatment and for ensuring proper follow up. Computed tomography and
magnetic resonance imaging are the main imaging tools. Each modality
showed its own advantages for assessment of local, regional or distant
staging.
The aim of this work is to emphasize the role of computed
tomography and magnetic resonance imaging in the evaluation of laryngeal
tumors.
During a period of 18 months from May 2016 to December 2017, the
study was carried out on 30 patients (26 males and 4 females) with age
ranged from 40 to 75 years old.
All patients were subjected to the following:
Detailed history taking.
Clinical examination & laboratory investigations.
Radiological examination: All patients underwent CT examination while
22 of them underwent additional MRI. Computed Tomography Virtual
endoscopy (CT VL) was done for 6 cases.
