What is a multifocal brain tumor?

Multifocal glioblastomas are tumors which have multiple discrete areas of contrast-enhancing tumor embedded with, or connected by, T2/FLAIR signal abnormality. Multifocal glioblastomas are considered to be part of the one tumor and are commonly encountered, accounting for 2-20% of all glioblastomas 3,4.

What is the life expectancy of a person with glioblastoma?
