It extends ventrally at different levels under the skin. It has been reported in many different breeds, but is most common in Rhodesian Ridgeback dogs. In this case, the dermoid sinus in the nasal region of a Rhodesian Ridgeback dog was characterized by computed tomography and magnetic resonance imaging. In this presentation, it is aimed to emphasize the importance of introducing the lesion and race and characterization using advanced imaging techniques in determining the treatment method.
