Idiopathic intracranial hypertension: Imaging and clinical fundamentals

Figure 12  Transverse sinus stenosis. A: For reference, a maximum-intensity-projection axial reconstruction of a 3D phase contrast magnetic resonance venography examination of the brain in a normal patient is provided. Note that the caliber of the transverse sinus bilaterally is within expected-normal limits (arrows); B and C: Display axial maximum-intensity-projection 3D phase contrast magnetic resonance venography reconstructions in different patients with signs and symptoms of increased intracranial pressure, demonstrating significant bilateral transverse sinus stenosis (arrows).
