Transcranial doppler sonography to monitor cerebral vasculitis.

We describe a patient with cerebral vasculitis treated with prednisone and cyclophosphamide and followed by serial transcranial Doppler sonography and arteriography. Proximal cerebral angiographic abnormalities correlated with transcranial Doppler abnormalities. The abnormalities gradually normalized with treatment and correlated with the findings of followup arteriography, which also showed improvement in the vascular morphology. Transcranial Doppler sonography is useful in following proximal cerebral vascular abnormalities in some cases of cerebral vasculitis.
