Abstract: RESUMO -Diversos fatores têm sido associados ao desenvolvimento de edema peritumoral nos meningiomas. Foram estudados os aspectos radiológicos e anátomo-patológicos de 51 meningiomas intracranianos operados no Hospital Universitário Clementino Fraga Filho (HUCFF). Dois terços dos meningiomas apresentavam edema perilesional. O tamanho dos meningiomas correlacionou-se com a presença de edema, sendo mais frequente nos meningiomas grandes (>4cm). A localização parece, também, influenciar no desenvolvimento do edem… Show more

“…This data contrasts partially with the literature because, although there are studies showing increased presence of PBE in more aggressive subtypes (atypical, malignant) compared to other subtypes 9 , most studies found no significant correlation between histological subtype and PBE 7,8,11 . PBE was found in 70.1% of cases.…”

“…Our study showed that tumors with PBE have bigger volumes than tumors without PBE. This finding is supported by the literature 6,7,9,11 , although some studies have not found a significant correlation between tumor volume and PBE 8,12 . Studies show that some patients with meningiomas have a decreased peritumoral blood flow and conclude that the edema may have an ischemic component, because of compression of adjacent brain tissue caused by the tumor 10 , in addition to vasogenic edema commonly described.…”
