case_images: Brain CT, MRI, MRA [Figure 1] and CTA [Figure 2] demonstrated a venous malformation communicating with the superior sagittal sinus under the scalp, without arterial feeder or nidus.

case_images: Following this, an intracranial standard venous phase catheter cerebral DSA was performed, while the lesion was temporarily obliterated by external compression, followed by a percutaneous embolization in one single-session with Onyx   (ev3, USA) [Figure 3], a nonadhesive liquid embolic agent.
