Leukoencephalopathy, Cystic, Without Megalencephaly

Description

Cystic leukoencephalopathy without megalencephaly is characterised by non-progressive leukoencephalopathy, bilateral cysts in the anterior part of the temporal lobe, cerebral white matter anomalies and severe psychomotor impairment. Less than 50 patients have been described in the literature so far. Inheritance is most likely autosomal recessive.
