Title: The Diagnostic Value of Magnetic Resonance Imaging in Children with Cranial Venous Sinus Thrombosis
Abstract: Objective To evaluate the clinical value of MRI in children with cerebral venous sinus thrombosis(CVST).Methods MRI findings of 15 children(11 male,4 female;age ranged from 10 days to 11 years;with mean of 3.9 years) with clinically diagnosed CVST were analyzed retrospectively.All the cases were performed with plain MRI and MRV.Only 1 patient underwent contrast enhanced MRI and contrast enhanced MRV.Results The thrombosis of transverse sinus was observed in 14 children,superior sagittal sinus in 12 cases,sigmoid sinus in 11 cases and sphenoparietal sinus involvement in 1 cases.CVST was manifested as iso-hyperintensity signal on T1WI and hyperintensity signal on T2Wl in 6 cases,iso-hyperintensity signal on T1WI and hypointensity signal on T2WI in 3 cases,isointensity both on T1WI and T2WI in 3 cases and hyperintensity signal on T1WI and isointensity on T2WI in 1 case,no obvious abnormal signal on T1WI and T2WI in 2 cases.Abnormal venous enhancement was found on contrast enhanced MRI in 1 cases.Contrast enhanced MRI showed ring like,triangle and parallel enhancement in wall of venous sinus,but venous sinus thrombosis did not enhanced with irregular filling defect or empty triangle.MRV showed the venous sinus as irregular,narrow,and discontinuous with collateral circulation formation,and many circuitous superficial cortical veins and the deep veins were seen near the involved venous sinus.Conclusion MRI combined with MRV,especially CE MRI and CE MRV are effective and noninvasive methods in the diagnosis of cerebral venous sinus thrombosis,which have important value in diagnosis,treatment and follow up for pediatric CVST.
