Thrombosis of the cranial venous sinuses and the cerebral cortical veins can lead to a distinct cerebrovascular disorder, which unlike arterial stroke, most often affects even young adults and children. Symptoms and clinical courses are highly variable, etiological factors are even more heterogeneous making cerebral cortical vein thrombosis (CVT) a unique clinical entity.We report three cases in which the initial presentation in our Emergency Department (ED) led to suspicion of CVT, had it diagnosed and recognised hyperhomocysteinemia.
