Abstract
Objective:To discuss the stripe sign of developmental venous anomaly and the cause of formation and diagnostic value.Materials and Methods: The clinical and imaging data of 8 cases of DVA conifrmed by contrast MRI were retrospectively analyzed.Results:In 8 cases, 3 cases were located at cerebellar hemisphere, 3 cases located beside the body of the lateral ventricle, 1 case located at the frontal lobe, 1 case located at the cerebellar hemisphere and the forth ventricle accompanying with cavernous hemangioma of cerebellum; All of 8 cases show low signal in T1WI and different high signal in the enhancement scanning, 4 cases show sea snake caput sign; In T2WI 5 cases show three groups of black and white stripes, 1 case shows round dot high signal, 2 cases show a single group of black and white stripe; In FLAIR 4 cases show three groups of black and white stripes.Conclusion:The cause of the formation of DVA stripe sign are lfow phase shift artifact and vascular pulsing artifact, and the stripe sign has important signiifcance in the diagnosis of DVA.关键词
