  • cranial
  • Magnetic resonance imaging (MRI) with gadolinium showed a 4-cm left-sided tumor of the posterior cranial fossa adjacent to the medial wall of the jugular foramen, with extension into the jugular foramen and likely occlusion of the sigmoid sinus (figure 2, A and B). Four-vessel cerebral angiography revealed a tumor blush in the jugular foramen (figure 3). (thefreelibrary.com)
