Head and neck cancer, particularly potentially unresectable advanced lesions, should be accurately evaluated because the results strongly impact on a treatment planning and patient outcomes. Radiologists must carefully detect the presence of deep invasion that may upstage a tumor to stage T4b and predict inoperability in cases of lymph node metastases. The most common and crucial factors associated with unresectability are carotid encasement, prevertebral fascia involvement and nasopharyngeal extension. Understanding the advantages, limitations, and appropriate criteria of each imaging modality (CT/MRI) for detecting the factors that determine unresectability improves decision-making regarding treatment, thus ensuring optimal therapeutic outcomes.

Factors associated with unresectable head and neck cancer (mainly, oro/hypopharyngeal and laryngeal cancer). Cases illustrating various patterns of unresectability. Some of the information is presented as a quiz, followed by case presentations with the patients’ treatment choice/outcome and histopathological findings: Resectability issues for primary disease: carotid encasement, prevertebral fascia involvement and nasopharyngeal extension Resectability issues for lymph node metastases: carotid encasement and invasion of the deep layer of the deep cervical fascia
