Imaging of the Head and Neck following Radiation Treatment.

Bottom Line: Squamous cell carcinoma of the head and neck occurs in approximately 40,000 patients annually in the United States and is often treated with radiation therapy.Radiological studies are obtained following treatment for head and neck malignancies to assess for recurrent tumor, posttreatment changes, and associated complications.As post-treatment imaging studies are often discussed at radiology/pathology working conferences, knowledge of the imaging appearance of radiation-associated changes in the head and neck and the terminology used by neuroradiologists may not only aid in interpretation of the pathologic specimen, but also assist in communications with neuroradiologists and referring clinicians.

ABSTRACT
Squamous cell carcinoma of the head and neck occurs in approximately 40,000 patients annually in the United States and is often treated with radiation therapy. Radiological studies are obtained following treatment for head and neck malignancies to assess for recurrent tumor, posttreatment changes, and associated complications. Radiation treatment creates a difficult clinical picture for oncologists, head and neck surgeons, neuroradiologists, and neuropathologists. As post-treatment imaging studies are often discussed at radiology/pathology working conferences, knowledge of the imaging appearance of radiation-associated changes in the head and neck and the terminology used by neuroradiologists may not only aid in interpretation of the pathologic specimen, but also assist in communications with neuroradiologists and referring clinicians.

Mentions: Within the first two weeks of treatment, mucosal irritation and edema may occur. In the pharynx and larynx, mucositis and submucosal edema result in prominent mucosal contrast enhancement with thickening of the epiglottis and aryepiglottic folds (Figure 1). Fibrosis and atrophy develop over many more months and do not normalize even years after treatment [7]. Necrosis of the pharynx and larynx peaks in the first 12 months after treatment, but has been reported to occur more than 10 years after radiation therapy [8].
