Angiographic signs of corpus callosal tumors: a reappraisal.
Angiographic findings of eleven corpus callosal tumors are analyzed. Three new angiographic signs are demonstration of the lateral ventricular roof veins, spreading of the septal veins, and actual demonstration of corpus callosal thickening. In contrast to traditional concepts, diagnostic abnormalities were angiographically demonstrated in all eleven cases. Biplane angiotomography is of vital importance in the angiographic diagnosis of this frequently subtle tumor.
