Article Figures & Data
Figures
- Fig 1.
CT, bone window, shows destruction of the right mastoid and cortical bone overlying the sigmoid sinus.
- Fig 2.
Postgadolinium axial T1-weighted MR image reveals an enhancing tumor causing substantial compression of the lumen of the sigmoid sinus.
- Fig 3.
Right ICA angiogram, frontal projection in the venous phase, demonstrates an 80% stenosis in the proximal part of the dominant right sigmoid sinus.
- Fig 4.
Control right ICA angiogram, lateral projection, obtained during test occlusion of the sigmoid sinus with a double-lumen angioplasty balloon inflated with a mixture of contrast agent and saline shows adequate drainage of the vein of Labbé without delay into the transverse sinus.
- Fig 5.
Control right ICA angiogram 2 days after permanent occlusion of the sigmoid sinus with a detachable balloon demonstrates patency of the transverse sinus with drainage of the vein of Labbé and jugular bulb via drainage of the inferior petrosal and basilar plexus.
