Water-soluble metabolites extracted from 60 surgically excised samples of various brain tumors and four nontumorous lobectomized brains were measured quantitatively using in vitro high-resolution magnetic resonance spectroscopy. A detailed MR spectrum-histology correlation study in a glioblastoma was made, to reveal MR spectral changes in accordance with the density of glioma cells. Furthermore...

A total of 311 patients with a unilateral acoustic neurinoma were operated on via the enlarged middle cranial fossa approach. A total tumor removal was achieved in 98% of cases. The mortality was 0.6%. Overall in acoustic neurinoma surgery, the percentage rates of meningitis (1.6%), cerebrospinal fluid fistula (1.6% requiring surgery), and neurological deficits were fairly low. The facial nerve...
