To explore the clinical and radiological features of bilateral thalamus venous infarction.
The cases definitely diagnosed as thalamus venous infarction were collected and the corresponding clinical and radiological data were retrospectively analyzed.
Four cases confirmed as thalamus venous infarction by digital substraction angiography (DSA) were collected. Bilateral thalamus lesions were detected in all cases by brain MRI scans which mainly presented as thalamus edema with high T1 and T2 signals with partial enhancement. Mild hemorrage was also shown in one case. Acute or subacute onset with clinical manifestations of headache, hypomnesia and hypersomnia were reported in all cases. The neurological examination showed conscious disturbance, memory impairment and positive Babinski sign. The venous thrombi were formed mainly in the transverse and the straight sinuses in 3 cases with the deep cerebral venous involved in 2 cases. All patients were improved after the anticoagulation therapy. Dural arteriovenous fi
