Computed tomographic studies of the basis pedunculi in chronic hemiplegic patients: topographic correlation between cerebral lesion and midbrain shrinkage.

abstract：:I report a 30-year-old woman with congenital cerebral venous dysgenesis with absence of the internal cerebral and basal veins and most of the cortical veins. Unlike the more common bilateral picture, she had involvement only on the left side, which delayed presentation and gave relatively mild symptoms. The embryologi...
