Vein of Galen Malformation With Sinus Occlusion on Magnetic Resonance Vessel Wall ImagingOA

A 17-year-old female patient presented with a 4-year history of recurrent spontaneous right frontotemporal headaches lasting approximately 30 min.Neurological examination and laboratory testing were unremarkable,and there was no history of hypertension,heart disease,or growth retardation.The subfigure(a)axial post-contrast image and subfigure(b)reconstructed image from magnetic resonance vessel wall imaging clearly demonstrated a vein of Galen malformation with bilateral sigmoid sinus occlusion(green arrows).The feeding arteries were clearly visible(yellow arrows),and diffuse,uniform enhancement of the venous wall and the walls of the draining veins was also observed after gadolinium administration(red arrows).
