High diagnostic value of gradient echo sequence in isolated cortical vein thrombosis

Abstract

Isolated cortical vein thrombosis is quite less common than dural venous sinus thrombosis. Its diagnosis is difficult and needs high index of suspicion clinically and on magnetic resonance imaging (MRI). A 38-year-old man presented with the history of three episodes of generalized seizures and weakness and sensory loss in the both upper limbs with headache. MRI brain with magnetic resonance venography (MRV) was performed. MRI brain showed hemorrhagic infarcts in bilateral frontoparietal region. Gradient echo sequence showed hypo-intense signal within thrombosed cortical veins. MRV showed paucity of cortical veins in involved areas suggestive of cortical vein thrombosis.
