Description

1) The precentral cerebellar vein begins between the lingula and the central lobe and runs upwards behind the anterior medullary velum in midline.<br>2) The normal course and configuration of this vein was described. The minimal distance from this vein to the posterior aspect of the clivus averaged 38 mm with a range of 31 to 43 mm as measured in 40 normal cases.<br>3) The deformities and displacement of this vein indicate the changes in the aqueduct and the upper part of the fourth ventricle caused by tumors of mesencephalon, pons and cerebellum.<br>4) Diagnostic value of this vein is highly evaluated in the vertebral angio-graphy by the authors.
