Radiology of cerebral vein occlusion without dural sinus occlusion.

The angiographic findings in eight patients having cerebral vein occlusion without dural sinus occlusion are presented. The role of other radiologic examinations is discussed. Occlusive disease involving the dural venous sinuses and/or cerebral veins is a more frequent cause of cerebral symptoms than is generally assumed. An increased awareness of the variable clinical and computed tomographic manifestations is recommended, with liberal recourse to more definitive angiography in suspected cases.
