Abstract

Four jugular foramen neurinomas studied by computed tomography and verified by surgery originated from the glossopharyngeal nerve. Characteristic CT findings were a mixed low and isodense extraaxial mass with ring-like enhancement in the cerebellopontine angle; enlargement of the jugular foramen, with smooth margins and a normal internal auditory canal; and an extracranial soft tissue mass extending through the jugular foramen.
