Axial contrast-enhanced CT scan demonstrates normal jugulodigastric lymph nodes bilaterally (curved arrows), which should not be confused with lesions originating in the parotid tail. Note the normal parotid tail tissue located anterolateral to the SCM (straight arrow). The lymph nodes lie anteromedial to the muscle. (Reprinted with permission from reference 1.)‏
