Abstract | OBJECTIVE: To identify the common MR Vfindings in the patient diagnosed intracranial veno-occlusive disease at Ramathibodi Hospital and to identify the underlying conditions that probably predisposed the patient to the intracranial veno-occlusive disease. MATERIAL AND METHOD: Sixty-four patients with clinically suggestive intracranial veno-occlusive disease who underwent MRV were reviewed in terms of signs and symptoms, MRV methods, MRV findings, and clinical diagnosis after report MRV In cases diagnosed to have intracranial veno-occlusive disease, the patients' records were reviewed to identify predisposing conditions. RESULTS: Thirty-four patients were diagnosed to have intracranial veno-occlusive disease. The common findings were lack of typical high flow signal from a sinus that did not appear aplastic or hypoplastic, frayed appearance of flow signal from a sinus at a later stage of the thrombus, and collateral vessels and cerebral hemorrhage. The common sites were superior sagittal sinus, and left and right transverse sinuses. Hypoplasia, a normal variation, was incidentally found in eight patients (12.5%). The most common hypoplastic site was the left transverse sinus. Contributing factors in patients diagnosed to have intracranial veno-occlusive disease in the present series were birth control pill in take, tumor ( meningioma, and malignant schwannoma of the scalp), blood dyscrasia, AVM, hypotension, and abscess. The causes of intracranial venous thrombosis could not be identified in seven patients (21%). CONCLUSION: The common MR Vfinding in acute intracranial veno-occlusive disease was lack of typical high flow signal from a sinus while frayed appearance of flow signal from a sinus was the common direct sign in chronic condition. In the present series, birth control pill intake was the most common contributing factor
