Our patient did well over the next year, but unfortunately CT scan of the neck in September 2011 demonstrated an enlarged peripherally enhanced soft tissue lesion within the submucosa of the right tongue base measuring 1.3 cm x 1.5 cm x 1.1 cm, which was concerning for recurrent disease (Figure 1).
After a 2-week course of stereotactic radiation, CT scan of the neck with contrast showing complete response to therapy.

He subsequently had a fiducial placed in the tongue base mass and underwent a course of hypofractionated image-guided stereotactic radiation therapy (Figures 3 and 4).
