Leukoencephalopathy

G93.4 | Encephalopathy, unspecified |
ICD-10 online (WHO version 2019) |
The leukoencephalopathy (from Greek λευκός leukós , German , white ' , Greek ἐγκέφαλος enképhalos , German , brain' and ancient Greek πάθεια pátheia , German , suffering ' ) is a collective term for diseases of the white matter of the brain . In contrast to leukodystrophy with defined clinical pictures, this overarching term includes all white matter diseases of whatever cause and type.
The term is often used for:
- Progressive multifocal leukoencephalopathy
- Hereditary diffuse leukoencephalopathy with axonal spheroids
- reversible posterior leukoencephalopathy syndrome (RPLS)
- Megalencephalic Leukodystrophy , Synonyms: MLC; Megalencephaly - cystic leukodystrophy; Vacuolating myelinonopathy with subcortical cysts; Van der Knapp syndrome
With leukoaraiosis subcortical or microangiopathic form of leukoencephalopathy is called.
root cause
Leukoencephalopathy can be caused by
- inflammatory diseases such as multiple sclerosis , CNS vasculitis
- infectious diseases such as a JC virus infection with severe immunodeficiency
- metabolic diseases such as Fabry disease
- congenital diseases such as leukodystrophies
- Hypoxic - ischemic damage (hypoxic ischemic encephalopathy) as in leucomalacia
- toxic influences such as in toxic leukoencephalopathy z. B. after radiotherapy or chemotherapy
- vascular diseases such as hypertensive leukoencephalopathy
In the context of syndromes
In various syndromes , leukoencephalopathy can be present as a feature:
- Autosomal recessive leukoencephalopathy-ischemic stroke-retinitis pigmentosa syndrome
- ARSAL , synonyms: ataxia, spastic, autosomal recessive, type 3; SPAX3
- Hypomyelinated leukodystrophy, autosomal recessive, C11ORF73-associated , synonyms: Hypomyelinated leukodystrophy due to Hikeshi deficiency; Hypomyelinated leukoencephalopathy, autosomal recessive, C11ORF73-associated
- CACH syndrome , synonyms: infantile ataxia with diffuse hypomyelination of the CNS; Leukoencephalopathy with loss of white matter in the brain; Myelinosis centralis diffusa; Cree leukoencephalopathy; English Leukoencephalopathy with vanishing white matter
- CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy)
- CARASIL , synonyms: Maeda syndrome; Cerebral arteriopathy with subcortical infarcts and leukoencephalopathy, autosomal recessive
- Leukencephalopathy, familial vascular, COL4A1-associated , synonyms: COL4A1-associated cerebral microangiopathy with hemorrhage; COL4A1-Associated Syndrome of Convoluted Retinal Arterioles with Infantile Hemiparesis and Leukoencephalopathy
- Cystic leukoencephalopathy without megalencephaly
- Leukoencephalopathy with bilateral anterior temporal lobe cysts
- Leukoencephalopathy with brain stem and spinal cord involvement - increased lactate (LBSL)
- Leukoencephalopathy with mild cerebellar ataxia and white matter edema
- Leukoencephalopathy - dystonia - motor neuropathy
- Leukoencephalopathy - metaphyseal chondrodysplasia
- Leukoencephalopathy - Palmoplantar Keratosis
- COXPD12 , synonyms: leukoencephalopathy-thalamus and brainstem abnormalities-high lactate syndrome; Combined defect of oxidative phosphorylation type 12; LTBL
- MNGIE syndrome
- Nasu Hakola disease
- Non-progressive predominantly posterior cavitating leukoencephalopathy with peripheral neuropathy
- Odontoleukodystrophy , Synonyms: Dento-leukoencephalopathy; Dentoleucoencephalopathy; Leukodystrophy with oligodontia
- PYCR2-dependent microcephaly-progressive leukoencephalopathy
- PADMAL , synonym: Pontine autosomal dominant microangiopathy with leukoencephalopathy
- Leukoencephalopathy, cavitating progressive
- Multifocal Progressive Leukoencephalopathy (PML)
- Retinal vasculopathy and cerebral leukoencephalopathy (RVCL)
- VPS11-associated autosomal recessive hypomyelinated leukodystrophy
diagnosis
The changes in the brain are recorded using medical imaging , usually magnetic resonance imaging or computed tomography .
