Dural venous occlusion can occur due to many factors as thrombosis, inflammatory conditions of the brain and tumors. Cerebral venous thrombosis (CVT) has long been a neglected entity because of complexities in diagnosis and non specific clinical presentation. Now-a-days due to the development of higher non invasive modalities and raised awareness, venous thrombosis is being diagnosed more frequently and more rapidly.
This study was carried out on 15 patients with suspected cerebral venous occlusion, 10 were females and five were males.
The youngest patient in this study was 40 days but the oldest one was 84 years old. The large number of patients was in the first year of life and a group of (30-60) years old.
The aim of the study was to assess cerebral venous occlusion or thrombosis by MRI and MRV.
The risk factors were puerperium, dehydration and post surgery complications. Five patients had unknown risk factors.
The clinical presentations of patients were different .Headache was the most frequent symptom in 10 patients (66.7%), followed by convulsion in six patients (40%), disturbed level of consciousness in five patients (33.3%),coma in four patients (26.7%), weakness of one limb in three patients (20%), blurring of vision and Papilledema in one patient (6.7%).
All the studied patients were subjected to MRI of the brain and MRV of cerebral venous system but five patients with suspected papilledema were subjected to fundal examination.
Examination of the 15 patients by MRI and MRV revealed thrombotic changes in 13cases (86.7%), focal brain tumor (meningioma) in two cases (13.3%).Incidentally noted hypo plastic LT transverse sinus in one patient of thrombosed cases as normal variant.
