Abstract

The basic anatomical and oncological properties of oropharyngeal cancer with appropriate radiological images are presented. The description is mainly divided into two categories; primary lesion and metastatic lymph nodes. Each of the categories is discussed in terms of the anatomy, oncology and current radiological imaging with emerging methods, such as FDG PET/CT and MRI diffusion imaging. Some interesting cases of lymphatic metastasis are also presented. A brief description on post-treatment observation of the disease is also given.

Keywords: Anatomy of oropharynx, HPV-related nodes, MRI diffusion imaging, oropharyngeal cancer, PET/CT, radiological images.
