Hemodynamic changes after distal splenorenal shunt studied by sequential angiography.

abstract：:In 24 CT studies in children with brain stem gliomas, the CT appearance was seen to vary with the tumor's physical characteristics. Infiltrative tumors produce diffuse enlargement of the brain stem; they are isodense with brain parenchyma or of decreased density and may show partial enhancement. Some gliomas grow foca...
