title: Neurological presentation of intravascular lymphoma: report of two cases and discussion of diagnostic challenges.
abstract: About a third of patients with intravascular lymphoma (IVL) present to the neurologist with symptoms mimicking thromboembolic events. Diagnosis is difficult, and often made postmortem. As remission may be induced in almost half of patients with combination chemotherapy, early diagnosis of this rare disease is essential. We report two cases of IVL. A 62-year-old male presented with hyperacute myelopathy followed by cortical ischaemic events. The diagnosis was reached with frontal cortical and meningeal biopsy. A 56-year-old female had symptoms of transient ischaemic events, subacute dementia, weight loss and fever. As the disease progressed, she developed nephrotic syndrome and thrombocytopenia. Diagnosis was made postmortem. Our cases illustrate that IVL should be considered in the differential diagnosis of cerebral and systemic vasculitis and subacute bacterial endocarditis. Literature suggests IVL can also mimic Creutzfeld-Jakob disease and paraneoplastic encephalomyelitis.
