  • Figure 1
    Pre-treatment MRI
     

    Axial and coronal MRI post-contrast T1W fat-saturated images show a left oropharyngeal primary extending into the parapharyngeal space, and left cervical chain metastatic lymph node mass.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

  • Figure 2
    Pre- and post-treatment FDG PET
     

    Pre-treatment half body FDG PET MIP showing avidity in the left oropharyngeal primary and left cervical chain lymph node mass consistent with locoregional spread. No FDG-avid distant metastatic disease was evident.

     
    Area of Interest: Head and neck; Imaging Technique: PET; Procedure: Diagnostic procedure; Special Focus: Metastases; Neoplasia;

    Post-treatment half body FDG PET MIP shows complete metabolic response of the primary site and regional lymph nodes. No FDG-avid distant metastatic disease was evident.

    Axial and coronal CT images demonstrate a focal region of irregular circumferential mural thickening in the distal ileum causing proximal small bowel obstruction. This was proven to be a focus of metastatic squamous...
