Cerebral venous angiomas.
Several unusual cases of cerebral venous angiomas as well as some characteristic cases are reported. The characteristic angiographic feature is that of a collection of dilated medullary veins draining into a single large draining vein, which appears first in the early venous phase and persists into the late venous phase of the arteriogram. Computed tomography (CT) was abnormal in 12/13 cases. The draining vein was the most common abnormality identified on CT. Coronal and sagittal reconstruction may be helpful in demonstrating the draining vein. A case of large twin venous angiomas, a case of hemorrhage from a venous angioma, and a case of a venous angioma with an incidentally associated glioblastoma are presented.
