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.

Radiation necrosis of the skull base with fistulous tract: Sagittal contrast-enhanced CT of the mandible bone (bone window) shows irregularity of the skull base (small arrow). In addition, there is a fistulous tract extending towards the oral cavity (large arrow).

Mentions: Osteoradionecrosis of the skull base may be suggested by destruction of the bone and may be extensive and symmetric or localized. The most common locations are the sphenoid bone, followed by the clivus, internal carotid canal, and temporal bone. Destruction of bone is present with sequestra present within or surrounding necrotic bone and small collections of air within the soft tissue adjacent to the necrotic bone [25] (Figure 4). Huang et al. [25] reported that the pathologic evaluation is very important because sometimes it is difficult to differentiate tumor recurrence from ORN or the two pathologic changes existed at the same time during the operation.
