Female, 77 years old, with history of left oral tongue squamous cell carcinoma stage III (pT1Nx), status post excision in 12/2015, status post adjuvent RT on 4/16, with recurrence in a left neck level II lymph node status post modified radical neck dissection in 11/2016. The left hemitongue is atrophic and somewhat diffusely T2 hyperintense. Mild postoperative deformity of the tongue is also seen. No discrete or clearly enhancing masslike lesion is appreciated in the operative bed. The aerodigestive mucosa as visualized is otherwise unremarkable.Mild edema is seen in the submental soft tissues. Findings are also demonstrated compatible with left neck dissection including volume loss and scarring through the fascial planes. The previously demonstrated left neck adenopathy is no longer visualized, and no new pathologic lymph nodes are identified.The left submandibular gland appears to have been resected. The residual salivary glands and the thyroid are free of focal lesions. Bone marrow signal of the spine shows evidence of prior radiotherapy but is otherwise unremarkable.
1.Findings are seen compatible with prior surgery of the left hemitongue. No definite residual or recurrent tumor is seen.2.Interval left neck dissection has been performed. The previously demonstrated adenopathy is no longer present. No new pathologic nodes are identified.
