Abstract
Intravascular large B cell lymphoma (IVLBCL) is a rare extranodal non-Hodgkin lymphoma characterized by proliferation of malignant cells within the lumen of small vessels, with a predilection for the central nervous system and the skin [1]. IVLBCL clinical course is highly aggressive, clinical signs and symptoms are not specific and may consist in neurological deficits, fever of unknown origin, cutaneous lesions, lacking of a typical neuroimaging pattern [1]. For all these reasons the diagnosis is frequently missed and the exitus is frequent, therefore post-mortem evaluation is necessary to clarify the clinical history. We present a case of IVLBCL in a 62-year-old female with unusual symptomatology, mimicking a vascular multinfarctual cerebropathy; post-mortem autopsy was diriment to define the nature of the disease. Immu- nohistochemical analysis for anti-CD20 revealed the ubiquitary presence of malignant lymphoid B-cells into the vessels of all organs analyzed, allowing the definitive diag- nosis. Although the diagnostic procedure for such pathology is still a matter for fur- ther studies, adequate interpretation of neuro-imaging and morphological findings, as well as of systemic symptoms can provide a right diagnostic hypothesis, suggest- ing focused biopsy in vivo .
