Thrombose veineuse cerebrale profonde : Ã propos de deux observations

Deep cerebral internal venous thrombosis was suspected based on the CT scan showing bilateral hypodensity in the thalamus and internal capsules. The diagnosis was confirmed on cerebral angiography. The patient was treated but died within 3 weeks of the onset of symptoms. The second patient had no obvious predisposing factors. She presented with confusion and fever. The diagnosis was strongly suggested by the CT scan, which showed spontaneous high density in the deep venous system associated with bilateral hypodensities in the thalamus and internal capsules. Venous MR angiography revealed obliteration of internal cerebral veins and the great vein of Galen. Ten days after appropriate therapy, the patient recovered completely.
