Female, 24 years old, with history of cT4 N1 Mx left tongue squamous cell carcinoma status post treatment. Anatomic distortion of the left hemitongue is again seen with perhaps some degree of volume loss when compared to prior exams. The previously extensive tongue mass with involvement of the floor of mouth, tongue base, left tonsil and soft palate continues to decrease in size and conspicuity. Accurate measurements are difficult, but for reference purposes, ill-defined left tongue enhancement now measures 29 x 22 mm x 27 mm (see image 16 series 13, and image 22 series 12), previously 55 x 40 x 40 mm.A reference left level IIa lymph node now measures 10 x 7 mm (image 24 series 5), previously 17 x 13 mm. No new or growing pathologic adenopathy is seen in the neck. Progressive treatment related findings are noted including reticulation of the subcutaneous fat and pharyngeal and supraglottic mucosal edema. The glandular tissues are unremarkable. Bone marrow signal characteristics are within normal limits.
Since the prior examination, the previously seen extensive tongue, tonsil and soft palate tumor continues to decrease in size. A reference left level IIa lymph node has also diminished in size. No new or progressive lesions are seen in a background of treatment related findings.
