title: A case of jugular foramen chordoma with extension to the neck: CT and MR findings.
abstract: We describe a case of jugular foramen chordoma with extracranial extension into the carotid, parapharyngeal, and perivertebral spaces through the jugular foramen. Although this type of extension is unusual, the differential diagnosis of head and neck tumors includes unusual extension of chordoma as well as extension of meningioma and neurinoma from the posterior skull base.
