Progressive Multifocal Leukoencephalopathy

Neurologic Clinics, 1984
PML is a progressive opportunistic infection of the CNS caused by a commonly occurring virus that may become manifest in the context of reduced host resistance in persons of any age. The authors review the disease and its causes, including a discussion of treatment attempts and differential diagnoses.

Toxic leukoencephalopathies

Toxic-metabolic encephalopathies are a group of disorders in which an exogenous or endogenous substance leads to transient or permanent neuronal damage. It is an important cause of potentially reversible acute encephalopathy syndrome. The signs and symptoms of toxic encephalopathies may be relatively nonspecific, and toxicologic tests are not always ...

Infectious leukoencephalopathies

Leukoencephalopathy from infectious agents may have a rapid course, such as human simplex virus encephalitis; however, in many diseases, it may take months or years before diagnosis, such as in subacute sclerosing panencephalitis or Whipple disease. There are wide geographic distributions and susceptible populations, including both immunocompetent and ...

Concentric Lacunar Leukoencephalopathy

Archives of Neurology, 1960
The group of diseases included under the general name of "leukoencephalopathy" comprises various pathoanatomic and pathogenic conditions. Their etiology is unknown. There is no satisfactory classification, and occasionally a new, equally obscure condition is added to this heterogeneous group. The purpose of this paper is to describe an unusual and not

Reversible Leukoencephalopathy Syndrome

The American Journal of Emergency Medicine, 2010
Reversible encephalopathy syndrome is a multietiological condition, the pathophysiology of which lies in the breach of the blood-brain barrier due to increased local cerebral perfusion pressure. Patients present clinically in nonspecific ways; acute computed tomography is often unrevealing, and as such, there should be a low threshold for early ...

Progressive Multifocal Leukoencephalopathy

Seminars in Neurology, 1999
Before the AIDS epidemic, progressive multifocal leukoencephalopathy (PML) was a rare disorder occurring most often in association with leukemia and lymphoma. Current estimates indicate that PML ultimately develops in up to 5% of all patients with AIDS.

Toxic Leukoencephalopathy

2012
The white matter of the brain is vulnerable to a wide variety of toxins. Leukoencephalopathy is being increasingly recognized in a number of different patient populations. The detection of early and subtle toxin effects has been facilitated by the advent of magnetic resonance imaging, which offers better resolution of white matter than other ...

MRI in methotrexate-related leukoencephalopathy: Disseminated necrotising leukoencephalopathy in comparison with mild leukoencephalopathy

Neuroradiology, 2003
We report two fatal cases of methotrexate (MTX)-induced disseminated necrotising leukoencephalopathy (DNL) in which MRI was repeated from the onset. Initial T2-weighted images showed multiple areas of high signal, mainly in deep cerebral white matter, which on follow-up, spread and coalesced to involve the entire white matter.

Cree Leukoencephalopathy and Other Leukoencephalopathies Involving Arcuate Fibers

Radiology, 2001
Editor: We read with great interest the article by Dr Alorainy and colleagues in the November 1999 issue of Radiology (1). The authors nicely presented computed tomographic and magnetic resonance (MR) imaging findings of a rare and lethal disorder, Cree leukoencephalopathy, in 12 patients whose diagnoses were made clinically or at autopsy.

Progressive Multifocal Leukoencephalopathy

Archives of Internal Medicine, 1963
Progressive multifocal leukoencephalopathy (PML) is a subacute demyelinating disease apparently resulting from the selective destruction of oligodendrocytes by papovaviruses. The pathology and pathogenesis of PML are distinct from those of the other slow infections of the human nervous system.
