Recurrent nasopharyngeal carcinoma: weight loss. There is an enhancing tumor in the left upper carotid space with extension through the widened left hypoglossal canal and cerebellomedullary cistern, as well as into the widened left jugular foramen. There is no mass effect upon the brainstem. The tumor measures up to approximately 30 mm in length and 25 mm in width. There is asymmetric effacement of the left lateral nasopharyngeal recess, without measurable tumor in this location. There is diffuse patchy enhancement of the clivus. There is mild scattered paranasal sinus mucosal thickening. The orbits are unremarkable. There is a partially empty sella. There is a disc-osteophyte complex at C3-4 that mildly indents the spinal cord.
Post-treatment findings in the nasopharyngeal region with tumor in the left upper carotid space with extension through the widened left hypoglossal canal and cerebellomedullary cistern, as well as into the widened left jugular foramen, which is compatible with recurrent nasopharyngeal carcinoma.
