Intractable headache after excision of an acoustic neuroma treated by stent revascularisation of the sigmoid sinus.

CSF pressures were normal but imaging studies showed acquired, severe narrowing of the sigmoid sinus where it traversed the surgical defect. Stenting the sinus gave a lasting clinical improvement.
