"Multifocal tumours have multiple discrete areas of contrast-enhancing tumour embedded with, or connected by, T2/FLAIR signal abnormality 5. Multifocal glioblastomas are considered part of a single tumour and are commonly encountered, accounting for ~17.5% (range 2-34%) of all glioblastomas 1,3,4. They have been shown to have a poorer prognosis than solitary tumours 1-3."
"Multicentric tumours are those that have multiple discrete areas of contrast-enhancing tumour without connecting T2/FLAIR signal abnormality 5. They are considered to represent separate, synchronous tumours ref. It is important to note that as imaging has improved, the frequency with which multicentric gliomas have been identified has reduced, as a result of being able to demonstrate connections between enhancing components more readily."
