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.
