Female, 28 years old, with T2 N0 right oral tongue squamous cell carcinoma status post CRT completed in 6/2009, status post salvage right partial glossectomy in 10/2009 with recurrent right oral tongue tumor. Findings are redemonstrated compatible with right hemiglossectomy and soft tissue flap repair, resection of the right coronoid process, and right neck dissection.Ill-defined enhancement seen previously along the right glossectomy margin is again seen, measuring up to 10 mm in the coronal plane (image 17 series 801), previously 13 mm. Nodular enhancement and T2 signal abnormality within the left oral tongue has significantly diminished in conspicuity. The dominant lateral tongue lesion now measures up to 14 mm (image 23 series 901), previously 23 mm.Reticulation and ill-defined signal abnormality within the subcutaneous tissues of the neck is likely a posttreatment response. No pathologic adenopathy is detected. The parotid and left submandibular glands are unremarkable. The right submandibular gland has likely been surgically excised. Lobular mucosal thickening in the right maxillary sinus has changed morphology but is not significantly larger than before. Marrow signal characteristics are unremarkable. Artifact from orthopedic instrumentation is partially visualized at the cervicothoracic junction.
1.Interval decrease in size of nodular enhancing tissue along the right glossectomy margin.2.Significant interval decrease in the size of nodular enhancement and signal abnormality within the left oral tongue.3.Demonstration of findings related to prior surgery and therapy.4.No definite pathologic adenopathy is observed.
