Abstract
Three cases of tumours involving the jugular foramen are reported; in one the growth was intracranial, in one extracranial and in the third it originated from the superior bulb of the internal jugular vein. The anatomy of the jugular foramen and the clinical symptoms consequent on the involvement of the IX, X and XI cranial nerves are described. Problems of diagnosis are discussed and the value of retrograde jugularography is stressed.
