1. Seventy-six-year-old man with acute venous thrombosis involving left parietal cortical vein (thrombus age approximately 1 day).
Seventy-six-year-old man with acute venous thrombosis involving left parietal cortical vein (thrombus age approximately 1 day). GRE image shows typical magnetic susceptibility effect with hypointense signal intensity and blooming in left parasagittal parietal cortical vein (long white arrow in A). Static 3D contrast-enhanced VIBE MR venographic images from combo-4D MRV are centered on region of interest (B and C). No evidence of cortical venous filling defect can be seen on axial image (B) and targeted axial thick-slab MIP reformation (thickness, 20 mm; C) of VIBE sequence in corresponding area. Likewise, this thrombosed cortical vein is not evident on 2D TOF MR venogram, as demonstrated by targeted axial thick-slab (thickness, 20 mm; D) and standard coronal whole-head (E) MIP reformations. On the latter image, additional thrombosis of right lateral sinus is depicted (short white arrows in E).
