Male, 54 years old, with recurrent T2 N2b squamous cell carcinoma of the base of the tongue, on protocol 12-1554 finished 4.5 cycles of TFHX on 5/4/16. Please evaluate and compare to previous scans. Since the prior examination, evidence of interval resection and soft tissue flap reconstruction are demonstrated involving the left oral tongue, floor of mouth and part of the left pharynx. Within this distorted postoperative background, no definite evidence of residual or recurrent tumor is seen. The residual native mucosa, and particularly that of the soft palate, is edematous likely related to surgery and treatment.Artifact related to orthopedic fixation is seen along the left paramedian mandible. Evidence of interval left neck dissection is seen including a very small seroma tracking through the surgical plane. No evidence of pathologic adenopathy is detected. No other masslike lesions are seen. The marrow signal characteristics are unremarkable.
Postoperative findings are demonstrated compatible with interval resection and reconstruction of the left oral tongue, floor of mouth and pharynx. Sequelae of left neck dissection are also noted. Within this postoperative background, no evidence of residual or recurrent primary tumor or pathologic adenopathy is seen.
