ABSTRACT
The chemical shift difference between the water resonance and the methyl resonance of N-acetylaspartate was used to determine the in vivo temperature in 43 patients with histologically proven brain tumors. Temperatures were also estimated from the contralateral side in 15 of these patients. There was a significant difference (p < 0.05) ] in temperature between meningiomas and the other tumors viz. low grade astrocytomas, grade IV astrocytomas and oligoastrocytomas. Temperature was also significantly different between the contralateral side and the meningiomas (p < 0.05).

Os autores relatam 5 casos de meningeoma cístico operados. Discutem os aspectos fisiopatológicos da formaçäo do cisto tumoral e sua classificaçäo com base na literatura revista. A histopatologia é avaliada, bem como a imunohistoquímica referente à proliferaçäo celular através da técnica do MIB1. Aspectos referentes à técnica operatória e conduta terapêutica säo analisados. Com este relato, as publicaçöes na literatura brasileira totalizam 14 meningeomas císticos.
