A case of the late cyst formation associated radiosurgery for arteriovenous malformation (AVM) treated with saireito

Abstract

Histopathology of the late cyst formation associated radiosurgery for arterio­venous malformation (AVM), showed proliferation of dilated vessels with fibrinoid degeneration associated with exudation of protein and bleeding. There were also the spontaneous regression cases. However, for the symptomatic cases were treated with surgery. We report a case that treated effectively with saireito for the inoperable late cyst.
