Abstract

PET-CT of the nasopharynx depicting not only intensive PET avidity in the right Rouvière lymph node (A: arrows) correlating with MRI findings but also increased FDG avidity at the level of the torus tubarius (B: arrows), on the right more than on the left and along the posterior nasopharyngeal wall. 3D PET image of increased metabolism along the lateral nasopharynx and torus tubarius (C: large arrow points to the right side, arrowhead to the left side; note also the avid Rouvière lymph node on the right side: short arrows). Tubarial gland location is shown in D (original scheme from Valstar, Matthijs, et al. Radiotherapy and Oncology, 154, 292-298: with permission).
