Figure 3. Left tonsillar squamous cell carcinoma, stage T2N2bM0.

Figure 3

A 37-year-old female with human papillomavirus-positive keratinizing squamous cell carcinoma of the left tonsil. The patient underwent transoral robotic radical tonsillectomy and neck dissection, followed by chemoradiation therapy with no recurrence in 3 years. Staging PET/CT (A) maximum intensity projection and (B) fused axial PET/CT images demonstrates intense metabolic activity within the left tonsil (standardized uptake value normalized to lean body mass of 10.4 and maximum standardized uptake value = 14.7) representing primary as well as foci of intense 18F-fluoro-2-deoxyglucose uptake fusing to several left cervical nodes (standardized uptake value normalized to lean body mass of 6.5 and maximum standardized uptake value = 9.1), consistent with regional nodal metastases and a total metabolic tumor volume of 7.5 ml (primary tumor 4.4 ml and lymph nodes 3.1 ml) (C).
