Papilledema in the metastatic jugular foramen syndrome.

In a patient with Ewing's tumor, bilateral papilledema developed along with a left jugular foramen syndrome. Plain tomograms demonstrated a metastasis at the base of the skull. A digital intravenous angiogram showed an occlusion of the left transverse sinus at the level of the jugular foramen. The papilledema was explained by an increase in the intracranial pressure due to the rapid obstruction of venous drainage by the metastasis.
