"Most frequent presenting symptoms are those of dysphagia or odynophagia. As these tumours often present late, other frequent presenting symptoms include a neck mass (either representing the tumour or nodal metastases; the latter being the presenting symptom in up to a quarter of patients), change in voice quality (due to involvement of the larynx of laryngeal innervation), or even systemic symptoms such as weight loss 2."
"Following irradiation, CT can be challenging, as irradiated mucosa often becomes oedematous, and soft tissue fibrosis may develop, obliterating or distorting normal fat planes and potentially mimicking tumour involvement 5."
"FDG PET-CT has an increasing role play in diagnosis, staging and follow-up of head and neck malignancies, allowing identification of metabolically active tumour deposits. As is the case with FDG-PET elsewhere size is a limitation, as is movement artifact and presence of dental amalgam artifact 4."
