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: Seventy percent of congenital neck masses are thyroglossal duct cysts [31]. These can occur anywhere along the course of the thyroglossal duct, usually at the level of the hyoid bone. Enlargement of pre-existing thyroglossal duct cysts following radiation therapy has been reported by Singh et al. [32]. They noted that the enlarged thyroglossal duct cyst became more fluidlike (Figure 8) and should not be misinterpreted as a tumor. When sonographyguided biopsy was performed, microscopic evaluation revealed proteinaceous fluid and histiocytes, and a diagnosis of a benign cyst was made. The enlargement is believed to have an inflammatory cause and shrinkage or stability of the cyst suggests resolution of the inflammation.
