Overview
CT Scan
The primary tumour typically appears as a solid soft tissue nodule or region of superficial thickening with increased enhancement. When the tumour extends beyond the confines of the pharynx, the surrounding fat planes are obliterated. It should be noted however that such stranding may be due to an inflammatory response rather than necessarily representing tumour invasion 6.
Careful assessment of cervical lymph nodes is essential as up to 75% of patients with hypopharyngeal SCCs have nodal metastases at the time of diagnosis 6.
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.
