Alterations of the Cerebral White Matter in a Middle-Aged Patient with Turner Syndrome: An MRI Study

A 52-year-old woman with intellectual disability was admitted to the hospital due to pneumonia. MRI of her brain showed diffuse hyperintensities on T(2)-weighted and fluid attenuated inversion recovery images in the bilateral cerebral white matter. Laboratory examination revealed sustained high levels of serum KL-6. Karyotyping revealed partial monosomy of the X chromosome. This is the first case showing diffuse white matter lesions in the brain, and sustained high levels of serum KL-6 in Turner syndrome.
