Demonstration of cystic brain tumors by angiotomography.
Cysts in cerebral tumours, as small as 1 cm in diameter, have been demonstrated by angiotomography with the sections made in the frontal plane. Two signs suggest a cystic lesion; a geometrically round, vessel-like outline in either the arterial or venous phase, resulting from a cystic cavity under pressure, and, during the parenchymatous phase, a radiolucent area having a radiological contrast identical to the non-injected hemisphere.
