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.

Chondronecrosis of the thyroid cartilage: (a) Axial contrast-enhanced CT of the thyroid cartilage (bone window) shows destruction of the left side of the cartilage (arrow). (b) Axial contrast-enhanced CT (soft tissue window) shows no evidence of an adjacent enhancing soft tissue mass (arrow).

Mentions: The larynx includes the thyroid, arytenoid, and cricoids cartilages and is involved in speech and swallowing. Computed tomography can have a role in the evaluation of patients showing signs of laryngeal edema and/or necrosis after radiation. The diagnosis of chondronecrosis of the larynx can be strongly suggested in cases of sloughing of the arytenoid cartilage, fragmentation and collapse of the thyroid cartilage, and the presence of gas bubbles around the cartilage [12] (Figure 5). On the other hand, if CT scans show asymmetric laryngeal tissues in a symptomatic patient, these findings may be used to target the biopsy into the most suspect area radiologically, which may be an enhancing mass, increasing the specificity of biopsy findings [12].
