abstract：:The angiographic differentiation of an intrinsic exophytic brainstem glioma from an extra-axial posterior fossa tumor is not always easy. The location of the basilar artery alone may not be significant. Displacement of the anterior pontomesencephalic vein anterior to the basilar artery appears to be a reliable indicat...
