History of cT2N0 squamous cell carcinoma of the posterior hypopharynx, HPV negative s/p chemoradiation completed 10/20/14 and now presenting with recurrent disease at the posterior pharyngeal wall. There are post-treatment findings in the neck, with swelling and diffuse enhancement in the hypopharyngeal region, stranding of the subcutaneous tissues and other fat planes, as well as hyperenhancement of the submandibular glands. There appears to be a more focal subcentimeter plaque-like area of mucosal enhancement and thickening along the left posterior pharyngeal wall. However, the prevertebral space appears to be intact. There is no evidence of significant cervical lymphadenopathy based on size criteria. The thyroid appears to be unremarkable. The cervical spine appears to be unremarkable. The major cervical arterial flow voids appear to be intact. The imaged intracranial structures are unremarkable.
Post-treatment findings in the neck with swelling and diffuse enhancement in the hypopharyngeal region. A more focal subcentimeter plaque-like area of mucosal enhancement and thickening along the left posterior pharyngeal wall may represent recurrent tumor, but is otherwise nonspecific. However, the prevertebral space appears to be intact.
