Vomiting and somnolence, generalized tonic and clonic convulsions with hepatomegaly, hyperammonemia, liver function impairment, and mild metabolic acidosis were the presenting signs. 3-hydroxyisovaleric, 3-methylglutaric, 3- methylglutaconic and 3-hydroxy-3-methylglutaric acids were detected in the urine by gas chromatography-mass spectrometry. 3-methylglutarylcarnitine was also identified in the urine by fast atom bombardment and tandem mass spectrometry. Therefore, the possibility of metabolic disease should be considered in neonates and infants with repeat attacks of Reye like syndrome and a history of similarly affected siblings.3-hydroxy-3-methylglutaric aciduria; Reye like syndrome[SDGs]SDG33 hydroxy 3 methylglutaric acid; hydroxymethylglutaryl coenzyme A synthase; aciduria; article; clinical examination; enzyme deficiency; human; pathophysiology; Reye syndrome; syndrome delineation; Female; Gas Chromatography-Mass Spectrometry; Humans; Infant; Meglutol; Recurrence; Reye Syndromejournal article109279632-s2.0-0033491729
