Nasopharyngeal cancer. There is an ill-defined right lateral nasopharyngeal recess mass that measures up to approximately 20 mm. The tumor abuts the right internal carotid artery, without encasement or evidence of perivascular spread. There is no evidence of tumor invasion of the skull base or intracranial extension. Indeed, the cavernous sinuses are intact. There is a partially necrotic right level 2B lymph node that measures 7 mm in short axis. There is also a mildly prominent and slightly heterogeneous right lateral retropharyngeal lymph node that measures 5 mm in short axis. The other cervical lymph nodes are unremarkable. There are right mastoid air cell effusions, likely related to mass effect upon the Eustachian tube orifice. There is a small right maxillary sinus retention cyst. The orbits are intact. The salivary glands are unremarkable. There is mild multilevel degenerative cervical spondylosis.
1. Right nasopharyngeal tumor measuring up to 20 mm without evidence of perivascular spread, invasion of the skull base or intracranial extension. 2. A partially necrotic right level 2B lymph node that measures 7 mm in short axis is compatible with metastatic disease. In addition, a mildly prominent right lateral retropharyngeal lymph node that measures 5 mm in short axis may also represent metastatic disease. The other cervical lymph nodes are unremarkable.
