Venous angiomas of the brain.
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.
