Multicentric Glioblastoma Multiforme-MRI


The actual incidence of true multicentric glioblastoma multiforme (GBM) varies between 2.4 and 4.9% of all GBMs. True multicentric tumors are described as widespread lesions in different lobes or hemispheres, which cannot be explained by spreading along the cerebrospinal fluid or blood pathways. We present here a case of multicentric GBM identified with MRI. This is a 73 yr old man, Look at the spread across the corpus callosum and along the white matter tracts in the posterior limb of the internal capsule and into cerebral peduncle.
