BackgroundWe describe a patient affected by a T-cell primary central nervous system lymphoma (PCNSL) with highly aberrant specific B-cell markers (CD79a and CD20). An unusual imaging presentation leads us to misdiagnose this lesion for a meningioma and perform surgical resection.Case DescriptionWe think that this infrequent anatomic presentation might be due to the aberrant specific B-cell markers (CD79a and CD20) genotype expression. We believe this case to be relevant in order to appreciate the diagnosis of cerebral lymphomas according to various presentations. We wonder whether it was not the aberrant genotype that contributed to this quirky presentation and ultimately if surgery in PCNSL should not be discussed?ConclusionsFurthermore, this case calls attention to the complexity of lineage assignment, imaging diagnosis, and treatment strategy in PCNSL.Copyright © 2019 Elsevier Inc.
