Case description
A 75-year-old female presented with a headache and was found to have a left-sided acute subdural hematoma, for which she underwent craniotomy for hematoma evacuation and cranioplasty. Follow-up imaging revealed a dural arteriovenous fistula (DAVF) with cortical venous drainage (CVD) into the left transverse sinus ( Figure 12.61.1 ). Gamma Knife radiosurgery (GKRS) was recommended as an initial treatment for the DAVF ( Figure 12.61.2 ), which was followed by embolization.
