Abstract
Mie examined the differences on intraoperative ultrasonography between 17 cases of meningioma and 29 of neurilemmoma, the common intradural extramedullary tumors. In meningiomas, cysts were rarely seen (in 12.5 %, P < 0.01 %) and echogenicity was high (in 82.3 %, P < 0.01 %). In neurilemmoma, many cysts were seen (72.5 %) and low echoes tended to b e more common (72.4 %, P < 0.01 %), In the neurilemmomas with high or isoechogenicity, Antoni A types, histologically rich in collagen fibre s, predominanted.
