Nasopharyngeal cancer. Head CT:There is no evidence of intracranial mass, hemorrhage or infarction. No enhancing abnormality is seen intracranially.Neck CT:There is a nasopharyngeal mass at the fossa of Rosenmueller on the left, measuring approximately 3.0 x 1.6-cm. extends to the left infratemporal fossa, at the region of the left foramen lacerum, causing erosion of the floor of the left carotid canal (image #19 of series 5). The soft tissue lesion is suspected to be partially encasing the left internal carotid canal, which can be better defined with MRI of the neck. There is no definite intracranial extension. There is adenopathy involving the left lateral retropharyngeal lymph nodes, and level 2 on the left.
Left nasopharyngeal mass with extension to the left infratemporal fossa and skull base destruction. It is likely partially encasing the left internal carotid canal. Adenopathy involving left lateral retropharyngeal node and left level 2. No definite intracranial extension.
