Primary central nervous system lymphoma: is absence of intratumoral hemorrhage a characteristic finding on MRI?

Abstract

Background. Previous studies have shown that intratumoral hemorrhage is a common finding in glioblastoma multiforme, but is rarely observed in primary central nervous system lymphoma. Our aim was to reevaluate whether intratumoral hemorrhage observed on T2-weighted imaging (T2WI) as gross intratumoral hemorrhage and on susceptibilityweighted imaging as intratumoral susceptibility signal can differentiate primary central nervous system lymphoma from glioblastoma multiforme.
