Large enhancing well defined oropharyngeal mass with bulk dimensions of 7.3 x 5.5 cm centred on the left side oropharynx with right-sided extension. The mass is causing severe narrowing of the oropharynx to less than 1 cm. The lesion extends superiorly to the left nasopharynx, causing asymmetry, and inferiorly to the base of the tongue, which it displaces. The mass abuts the prevertebral space without invasion of the longus capiti.
High T2 signal and enhancement in left masticator space surrounding the pterygoids muscles and mandibular ramus suggestive of disease extension.
Multiple bilateral enlarged cervical lymph nodes, the largest on the left measures 9.7 cm centred on the left submandibular space and compresses both the submandibular and parotid glands. 2.2 cm right level Ib node.
The carotid sheath vessels and left retromandibular vessels are intact.
No lower visualised intracranial extension is seen. Both parotid and thyroid glands are normal.
