Figure 2.

The 2D TOF (A) and contrast enhancing MR venography (B) show decreased caliber of left transverse sinus (arrow). The source images of CEMRV (C, D) detect filling defects from the thrombus within the sinus (arrow). The venous phase of the vertebral angiogram (E) shows the small caliber of the left transverse sinus. During intracranial venous thrombolytic treatment (F), the venous sinus is reopened with residual thrombus (white arrow). The tip of the micro-catheter is in position (black arrow).
