Multiple recurrent oral cancer s/p two major resections with free flap reconstruction and XRT with dermal metastasis with good response clinically. There are postoperative findings, including right hemiglossectomy and floor of mouth dissection with soft tissue flap reconstruction, mandibular reconstruction, and bilateral neck dissection. There is marked interval decrease in size of the enhancing mass along the posterolateral margin of the flap in the right oral cavity, with erosion of the adjacent mandible. Indeed, the tumor now measures up to approximately 15 mm, previously 45 mm. There is no evidence of significant lymphadenopathy or evidence of new mass lesions in the neck. There is a small amount of fluid signal in the right mastoid air cells. The imaged intracranial structures and orbits are unremarkable. There is partially imaged thoracic scoliosis.
Extensive post-treatment findings in the oral cavity region with marked interval decrease in size of the recurrent tumor along the posterior margin of the surgical flap with adjacent right mandible erosion.
