ABSTRACT
BACKGROUND Vanishing white matter disease (VWMD) - also known as childhood ataxia with central nervous system hypomyelination - is one of the most commonly inherited white matter diseases in children. Notably, a course of chronic progressive disease with episodes of rapid and major stress-induced neurological deterioration, such as fever and minor head trauma, is a typical clinical feature of VWMD. The combination of clinical features with specific magnetic resonance imaging findings, including diffuse and extensive white matter lesions with rarefaction or cystic destruction, could recommend a genetic diagnosis. However, VWMD is phenotypically diverse and can affect individuals of all ages. CASE REPORT A 29-year-old female patient presented with recent aggravation in gait disturbance. She had progressive movement disorder, with symptoms ranging from hand tremors to upper- and lower-extremity weakness, for 5 years. Whole-exome sequencing was performed to confirm the diagnosis of VWMD, and it revealed a mutation in homozygous eIF2B2 gene. The temporal evolution of VWMD observed in the patient for 17 years (from the age of 12 to 29 years) indicated an increased extent of T2 white matter hyperintensity in the cerebrum into the cerebellum and an increased amount of dark signal intensities in the globus pallidus and dentate nucleus. Moreover, a T2*-weighted imaging (WI) scan revealed diffuse, linear, and symmetrical hypointensity along the juxtacortical white matter on the magnification view. CONCLUSIONS This is the case report about rare and unusual finding of diffuse linear juxtacortical white matter hypointensity on T2*-WI scan as a potential radiographic marker for adult-onset VWMD.
