Anterior pontomesencephalic vein and basilar artery in exophytic brainstem gilioma
Radiology
|August 1, 1977
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 indicator of an intrinsic exophytic brainstem glioma.
