L-2-hydroxyglutaric aciduria (L-2-HGA) is a rare, autosomal recessive organic aciduria with increased levels of L-2hydroxyglutaric acid in the urine and other body fluids. Clinical presentation includes developmental delay, epilepsy, and typical neuroimaging findings.

This is a report of the clinical, neuroimaging, and biochemical findings of the first diagnosed case of L-2-hydroxyglutaric aciduria in the Philippines. This paper likewise reaffirms the importance of locally available biochemical tests in diagnosing inborn error of metabolism.
