Female, 62 years old, with newly diagnosed base of tongue cancer, compare to outside. A bulky enhancing mass is evident involving the tongue base bilaterally measuring up to 40 mm when assessed in the transverse plane (image 31 series 12). This lesion extends into the floor of mouth bilaterally as well as into the left oral tongue and perhaps a small portion of the right oral tongue as well. The exact boundaries of this infiltrative spread are difficult to assess though the lesion potentially occupies a majority of the tongue. Ulceration of the left oral tongue is demonstrated. The lesion effaces the vallecula and is inseparable from the free edge of the epiglottis. No definite involvement of the supraglottic larynx is seen.Two left level Ib lymph nodes are subjectively prominent but they do not meet imaging criteria for pathologic enlargement. No additional pathologic adenopathy is detected. The salivary glands and thyroid are unremarkable. Bone marrow signal characteristics are unremarkable.
1.A large mass is evident centered on the tongue base but with extensive infiltration of the floor of mouth and oral tongue.2.No pathologic adenopathy is identified by size criteria.
