title: Venous angiomas of the brain.
abstract: Two cases of venous angioma of the brain are presented. Both were discovered by computed tomography and diagnosed by angiography. The lesion was located in the right frontal lobe in 1 case and in the left cerebellar hemisphere in the other. Neither was operated on because of the deep location or extent of the lesion. The 2 cases showed significant angiographic and hemodynamic differences. The literature on venous angiomas of the brain is reviewed. We proposed classifying venous angiomas into two subgroups based on angiographic findings: those with early-appearing vessels and those without. No significant differences in clinical manifestations were noted between these two subgroups in spite of the hemodynamic differences.
