Postoperative and postradiation changes on imaging

Area of Science:

• Radiology
• Oncology
• Head and Neck Surgery

Background:

• Post-treatment imaging of the neck is crucial for evaluating patients after head and neck cancer therapies.
• Distinguishing normal post-surgical and post-chemoradiation changes from tumor recurrence can be challenging.

Purpose of the Study:

• To present the typical imaging appearance of the neck after common surgical procedures and chemoradiation therapy.
• To provide illustrated examples for recognizing complications and disease recurrence.

Main Methods:

• Review of imaging findings in patients who underwent surgical procedures and/or chemoradiation for head and neck cancer.
• Detailed description of expected changes for each surgical technique.
• Inclusion of representative images demonstrating normal findings, complications, and recurrence.

Main Results:

• Detailed descriptions of the normal post-therapy neck appearance are provided for various surgical approaches.
• Illustrated examples highlight common complications such as infection, fluid collections, and radiation-induced changes.
• Visual aids demonstrate characteristic features of disease recurrence in the post-treatment setting.

Conclusions:

• Familiarity with normal post-therapy imaging is essential for accurate interpretation.
• Radiologists and clinicians should be aware of potential complications and imaging features of recurrence.
• This visual guide assists in the effective management of head and neck cancer patients post-treatment.
