By definition, there is no co-existing systemic disease at the time of diagnosis, distinguishing it from CNS involvement from systemic lymphoma (secondary CNS lymphoma). On imaging, PCNSL characteristically is identified as a CT hyperdense enhancing supratentorial mass, with MRI T1 hypointense, T2 iso- to hypointense, vivid homogeneous enhancement and restricted diffusion.

Learn about the risks factors, diagnosis, and treatment of primary CNS. Introduction. Primary central nervous system lymphoma PCNSL is a rare cancer accounting for less than 3% of brain tumors CBTRUS, 2009. The vast majority of PCNSLs are diffuse large B-cell lymphomas, and unlike systemic diffuse large B-cell non-Hodgkin lymphoma NHL, PCNSL remains confined to the CNS brain parenchyma, leptomeninges, eyes and the spinal cord in most patients. Primary CNS lymphoma PCNSL is a rare form of extranodal non-Hodgkin lymphoma that is typically confined to the brain, eyes, and cerebrospinal fluid without evidence of systemic spread. The prognosis of patients with PCNSL has improved during the last decades with the introduction of high-dose methotrexate. However, despite recent progress, results after treatment are durable in half of. The current (2016) WHO classification of CNS tumors divides CNS lymphomas into a number of subtypes, based on the cell of origin and histological features. Usually, there is relatively little associated vasogenic edema and no central necrosis, although it is important to note that in immunocompromised individuals appearances tend to be more heterogeneous.
