T2N0 right oral tongue squamous cell carcinoma treated with CRT completed in 6/2009 with right partial glossectomy for salvage in 10/2009 with recurrent right oral tongue tumor treated with chemoradiation. There are post-treatment findings in the oral cavity, including interval post-radiation effects and right neck dissection with radial forearm flap reconstruction. There is interval decrease in size and enhancement of an ill-defined lesion in the right oral tongue along the margins of the glossectomy site that measures up to 14 mm, previously 18 mm. However, there is new patchy high T2 signal and enhancement in the left anterior oral tongue that measures up to approximately 23 mm. There is no evidence of significant lymphadenopathy in the neck. The remaining salivary glands are unremarkable. The thyroid gland also appears unremarkable. There are upper thoracic spinal rods that produce susceptibility effect in the region. There is a right maxillary sinus retention cyst. The major cervical flow voids appear to be intact. The imaged intracranial structures, orbits, and facial soft tissues appear unremarkable.
1. Interval decrease in size and development of necrosis in the recurrent right oral tongue mass following treatment.2. New patchy high T2 signal and enhancement in the left anterior oral tongue may represent treatment-related effects.
