Imaging of the post-treatment neck

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Post-treatment imaging of the neck presents complexities due to expected treatment-related changes and potential complications.
• Understanding these appearances is vital for accurate interpretation and patient management.

Purpose of the Study:

• To outline the common imaging findings following neck cancer treatment, including radiation therapy and surgery.
• To highlight potential complications such as osteoradionecrosis, chondronecrosis, and accelerated atherosclerosis.
• To emphasize the importance of identifying signs of tumor recurrence and nodal recurrence.

Main Methods:

• Review of common imaging findings after radiation therapy (e.g., soft-tissue edema, skin thickening).
• Discussion of imaging features associated with surgical interventions, including flap reconstructions.
• Identification of imaging indicators for tumor recurrence (new enhancement, bone/cartilage erosion) and nodal recurrence.

Main Results:

• Radiation therapy commonly causes soft-tissue edema and skin/platysma thickening.
• Complications like osteoradionecrosis, chondronecrosis, and accelerated atherosclerosis can be visualized on imaging.
• New enhancing nodules or erosions may indicate tumor recurrence; nodal recurrence assessment is also critical.

Conclusions:

• A thorough understanding of post-treatment neck imaging appearances and complications is essential.
• Standardized reporting approaches can enhance accuracy and aid in treatment decisions for neck cancer patients.
