Cortical vein thrombosis is a subset of cerebral venous thrombosis involving the superficial cerebral veins besides the dural sinus, often coexisting with deep cerebral vein thrombosis or dural venous sinus thrombosis. 

This case illustrates left frontal cortical veins and superior sagittal sinus thrombosis managed clinically with no signs of chronic thrombosis on the MRA follow-up. However, some prominent transmedullary veins on the left caught our attention on this exam. They probably represent an anatomical variation, although follow-up with MRA was recommended as surveillance for possible fistula complication.
