Primary central nervous system lymphoma (PCNSL) is a rare and aggressive extra-nodal non-Hodgkin lymphoma (NHL). It must be confined to the brain, eyes, spinal cord or leptomeninges without systemic involvement at the time of diagnosis. Disease confined to the cerebrospinal fluid (CSF) is a rare form of presentation and poses a particular diagnostic challenge. We present the case of an 82-year-old man admitted to hospital because of an acute confusional state, later revealed to be due to PCNSL with exclusive leptomeningeal involvement. The diagnostic process was further impaired (or, perhaps, aided?) by the onset of a COVID-19 outbreak on the ward.
