Background: L-2-Hydroxyglutaric aciduria is a rare progressive neurometabolic disorder of childhood inherited as an autosomal recessive trait. Urine organic-acid screening is necessary for its diagnosis. Although it is a disorder of childhood, recently adult cases have been reported.
Cases: Here we report 4 adult patients in whom diagnoses were established in adulthood. These patients had some interesting features. First, their diagnoses were delayed until adulthood because of mild clinical symptoms. In such cases, the typical MRI findings are the best diagnostic clue for L-2-Hydroxyglutaric aciduria. Second, there was a correlation between the severity of the clinical course and the extent of MRI findings. The cerebral white-matter lesions were diffuse and confluent on the MRI of 3 of the 4 patients, who also experienced a rapidly progressive clinical decline. Third, there were different clinical presentations even within the same family.
Conclusions: For the evaluation of patients with symptoms referable to cerebellar, pyramidal, extrapyramidal, or cognitive impairment as well as seizures associated with subcortical white-matter and symmetrical dentate nuclei and basal ganglia involvement on MRI, urine organic acid analysis should be included in the evaluation, regardless of patient's age.
