Cerebral venous thrombosis (CVT) is a rare form of venous thromboembolism. The presentation of symptoms is highly variable in this disease. The findings on MRI vary depending on the age of the thrombus within the vessel. We report a 53-year-old male patient with CVT who presented with a sudden-onset grand mal seizure and limb paralysis. Primary MRI presented long T1 long T2 signals, persistent high signals on DWI and ADC maps in the cortex of right frontal lobe. Contrast-enhanced MR detected a lesion with ring-like enhancement in right frontal lobe. His symptoms were significantly improved with anticoagulant therapy of Warfarin. Our findings represent the description of abnormal MRI contrast enhancing tumor-like masses. CVT should be added to the differential diagnosis of supratentorial ring-enhancing lesions.
