Methods Hospital based descriptive cross-sectional study was used at Tikur Anbessa specialized hospital from 2016-2019. The study participants were all patients with laryngeal mass who came to oncology department & radiology department at TASH. Data was collected from cancer registry in the oncology department as well as by reviewing imaging reports of patients with laryngeal mass who came to radiology and oncology department using structured questionnaire. The data was analyzed using SPSS software version 24.4 and results presented using text, tables and graphs. Result The study showed that of the 90 patients who were included in the study had age range from 24 yrs. to a maximum of 85 yrs. with a mean age of 51.5 years with (±14 SD). 77 (85.6% presented with hoarseness of voice and Among those 34 cases for which risk factors were specified 23 (67.6%) had cigarette smoking as risk factor while 12 (35.3%) had alcohol as risk factor. Out of the 79 cases with laryngeal sub sites described, 38 (48.1%) were transglottic, 27 (34.2%) glottic and 12 (15.2%) were supraglottic. 46 (51.1%) patients had extra laryngeal spread, 18 (20%) had no extra laryngeal spread, and for 26 (28.9%) cases it was not specified. Laryngoscopic cases of glottic location correlates with 46.2% of imaging cases of glottis cancer with the rest 46.2% being transglottic and 7.7% being supraglotic on imaging.en-USCT imaging patterns, laryngeal cancerThesis
