A 50-year-old man developed cauda equina syndrome of unknown etiology that was stable for 20 months. Two months prior to sudden death, he experienced new back pain, confusion, seizures, and multiple cranial nerve palsies. Neuropathologic examination revealed angiotropic lymphoma without parenchymal involvement or infarcts in the brain, spinal cord, and muscle. In addition, nerve roots in the cauda equina contained angiotropic lymphoma and infarcts of various ages. Angiotropic lymphoma should be considered as a cause of cauda equina syndrome and of disorders that affect the central and peripheral nervous systems concurrently.

A 60-year-old white man presented with aphasia, seizures, paraparesis, and incontinence. His serologic and hematologic profiles were unremarkable. His cerebrospinal fluid showed pleocytosis, increased daily central nervous system IgG synthesis, increased myelin basic protein, and negative cytology and cultures. Cerebral computed tomography exhibited multiple areas of hypodensity but spinal computed tomography and myelography showed no abnormalities. Cranial and spinal magnetic resonance imaging revealed areas of increased signal on T2-weighted images. The use of gadolinium-pentetic acid on T1-weighted images delineated smaller areas of cortical enhancement with surrounding rim of decreased signal. Brain biopsy showed intravascular malignant cells positive for leukocyte common antigen and B-cell markers. The diagnosis was neoplastic angioendotheliomatosis (intravascular lymphomatosis). To our knowledge, this is the first report on the use of both cranial and spinal magnetic resonance imaging in this condition.

Intravascular lymphomatosis (i.v.l.) is a rare condition in which neoplastic cells preferentially infiltrate blood vessels of the central nervous system. Nonspecific symptoms associated with i.v.l. include dementia, seizures, and multifocal cerebrovascular events. i.v.l. was discovered at autopsy of a patient whose neurological deficits were predated by a particularly aggressive form of Mycobacterium marinum soft-tissue infection. It is speculated that i.v.l. may have had an occult effect on the patient's cell-mediated immunity that predisposed him to this normally innocuous mycobacteria.

Intravascular lymphomatosis is an uncommon lymphoproliferative disorder characterised by intravascular distribution of neoplastic lymphoid cells (B- or T-lymphocites), what leads to occlusion of small vessels and causes signs and symptoms of disorder. Its initial predilection sites are the brain or the skin, and hematopoetic organs are usually spared. The signs and symptoms of the disorder are attributed to vascular occlusion. Clinical course is fatal, besides therapy. In our case disorder has started with partial epileptic seizures with secundar generalisation, and after that with motor aphasia, right hemiparesis, urinary incontinence and cognitive changes. She was hospitalized for several times, completely investigated, but with no conclusion. Seven months after apperance of symptoms, she died. And diagnosis was determined at autopsy. A myriad of neurological and systemic manifestations are putting us in an unequal position with this fatal disease. Early diagnosis can increase survival and decrease intensity of symptoms. So every new case is important as warning that we must not forget about this disease.

Intravascular lymphomatosis is a rare extra-nodal form of diffuse, large B-cell non-Hodgkin's lymphoma that causes a myriad of neurological symptoms, including focal neurological deficits, cognitive decline, and seizure. Intravascular lymphomatosis is difficult to make ante-mortem diagnosis because of its variable clinical presentation and non-specific laboratory findings. Neuroimaging findings also vary widely in patients of intravascular lymphomatosis. We present, herein, a patient with rapidly deteriorating neurological deficit whose brain MRI revealed rapidly progressing white matter diseases. This patient was diagnosed and treated as having a cerebral demyelinating disorder. Intravascular lymphomatosis involving multiple organs was finally diagnosed after autopsy.

Intravascular large B-cell lymphoma (IVL) is a rare form of diffuse large B cell lymphoma (DBCL) frequently presenting with skin and/or central nervous system (CNS) involvement. IVL involves CNS in 75 - 85% of patients and neurological symptoms include sensory and motor deficits or neuropathies, meningoradiculitis, paresthesia, hypostenia, aphasia, dysarthria, hemiparesis, seizures, transient visual loss, vertigo and impaired cognitive function. Neuroimaging discloses CNS involvement only in half of patients with neurological symptoms because there are no pathognomonic neuroradiological findings for IVL; ischemic foci are the most common presentation pattern and therefore vasculitis is the most common differential diagnosis. According to all mentioned data, diagnosis of CNS IVL requires a histopathological confirmation. Brain biopsy is absolutely indicated in patients with progressive neurological deterioration with unclear abnormalities in cerebral MR imaging. A general policy is that patients with IVL should be considered to have disseminated disease and should be treated with systemic chemotherapy. In younger patients with unfavorable features the high-dose chemotherapy with autologous stem cell transplantation should be used. Nevertheless, the course of IVL is rapidly progressive and ultimately fatal.

Intravascular lymphomatosis (IVL) is known to affect both hemispheres of the brain and manifests clinically as seizures or dementia. To our knowledge, there have been no cases in which acute hemispheric dysfunction is manifested in IVL. We present a 54-year-old man who showed steroid responsive acute hemispheric dysfunction. A technetium 99m-ethyl cysteinate dimer single-photon emission computed tomographic scan of the brain revealed hypoperfusion in the right hemisphere. The bone marrow biopsy specimen confirmed malignant lymphoid cells in vessels, which suggested IVL. Our case signifies the diversity of clinical manifestations in IVL.

Intravascular B-cell lymphoma is a rare, aggressive subtype of diffuse large B-cell lymphoma that presents insidiously with symptoms relating to organ involvement. We present the case of a male in his late 40s who presented with fluctuating neurological symptoms including episodes of altered upper-limb sensation, seizures and psychotic phenomena. These symptoms and signs were associated with fleeting brain lesions on neuroimaging. A brain biopsy confirmed the diagnosis of intravascular B-cell lymphoma and he was treated with CHOP chemotherapy (cyclophosphamide, hydroxydaunorubicin, vincristine and prednisolone). Two years later, he remains well. Timely diagnosis and aggressive treatment provides an optimal chance of long-term survival so it is essential to recognise early disease characteristics.

A 10-year-old, castrated male domestic short-haired cat was presented with an acute history of seizures, lethargy, anorexia, vomiting, and dyspnea. Magnetic resonance imaging of the brain showed multifocal areas of gray matter T2-weighted hyperintensity. The lesions did not enhance with intravenous contrast. The cat was diagnosed at necropsy with feline systemic reactive angioendotheliomatosis, a rare vascular proliferative disorder for which a treatment has not yet been identified. This report is the first to describe associated magnetic resonance imaging changes for this disease.
