title: Intravascular large B cell lymphoma: an elusive cause of pyrexia of unknown origin diagnosed postmortem.
abstract: Intravascular large B cell lymphoma (IVLBCL) is a rare cause of pyrexia of unknown origin. Because of its protean clinical manifestations, diagnosis is elusive and is often made postmortem. We report here a case of IVLBCL that evaded diagnosis despite multiple investigations in vivo for pyrexia of unknown origin over a 5&#x2010;month period.
