Surfer's ear or exostosis of the external auditory canal (EAC) is a slowly progressive disease caused by benign bone growth resulting from chronic exposure to cold water. It is uncommon, its prevalence was 6.3 per 1000 people. We report the case of a 37-year-old male subject referred by the Otorhinolaryngology department of the University Hospital Center "Gabriel TOURE" to the radiology and medical imaging department of the medical clinic "LES ETOILES" for a computed tomography (CT) scan of the petrous bones in the context of a bilateral intra-auricular mass. He had no particular history. The CT scan, performed without injection of contrast agent with axial and coronal reconstruction, had objectified a bony outgrowth at the level of the rounded bilateral tympanic bone with a wide implantation base concluding in surfer's ear. The aim of our work was to study the contribution of CT scan of rocks in the diagnostic management of surfer's ear.
