Abstract
IntroductionCerebral venous occlusion (CVO) means intraluminal obstruction by cerebral venous thrombosis (CVT) or external compression. The differential diagnosis is broad including stroke, brain capillary telangiectasia, contusion, hypertensive hemorrhage, metastases and venous vascular malformations. MRI in conjunction with MRV is considered the modality of choice in diagnosis of CVO. ObjectiveTo assess the role of magnetic resonance venography in the evaluation of cerebral veins and sinuses occlusion. MethodsThe study was conducted on 15 patients with cerebral venous occlusion and subjected to MRI and MRV. ResultsThe study included 13 patients with cerebral venous occlusion due to thrombosis and two patients with occlusion by tumors (meningioma). ConclusionMRI in conjunction with MRV is considered an accurate, safe, non-invasive, non-ionizing diagnostic modality in assessing CVO. It can assess parenchymal lesions and detect intraluminal small thrombi and its extension.
