A case of isovaleric acidemia appearing as diabetic ketoacidosis with acute encephalopathy and pancytopenia was reported. A three-year-old male patient, with mild psychomotor retardation, had recurrent bouts of acute encephalopathy and pancytopenia after episodes of upper respiratory infection. At admission, he had vomiting associated with dehydration, acidosis, ketonuria, coma and a pungent, rather unpleasant odor. Laboratory features included hyperglycemia, hyperammonemia, hyperamylasemia, hypocalcemia, neutropenia, thrombocytopenia and subsequent anemia. Urine organic acid profiles showed profuse amount of 3-beta-hydroxyisovaleric acid (295 mg/ml) and isovalerylglycine (616 mg/ml) by gas chromatography-mass spectrometry. Levels of amino acids in the serum and urine were normal. The patient received treatment with rehydration and insulin, with rapid improvement. After the acute illness, blood glucose levels returned to normal. The patient was doing well on a low-protein diet in recent 3 months.

Isovaleric acidaemia is an inborn error of leucine metabolism due to deficiency of isovaleryl-CoA dehydrogenase, which results in accumulation of isovaleric acid in body fluids. There are acute and chronic-intermittent forms of the disease. We present the cranial CT and MRI findings of a 19-month-old girl with the chronic-intermittent form of isovaleric acidaemia. She presented with severe metabolic acidosis, hyperglycaemia, glycosuria, ketonuria and acute encephalopathy. Cranial CT revealed bilateral hypodensity of the globi pallidi. MRI showed signal changes in the globi pallidi and corticospinal tracts of the mesencephalon, which were hypointense on T1-weighted and hyperintense on T2-weighted images.

Isovaleric acidemia (IVA) is characterized by periodic vomiting, lethargy, coma, ketoacidosis and a 'sweaty feet' odor. Hyperglycemia, ketonemia, ketonuria and metabolic acidosis are the main clinical features of diabetic ketoacidosis (DKA) and these same symptoms can also be seen in acute attacks of metabolic diseases. We report a 2-year-old patient who presented with acute encephalopathy, hyperglycemia, metabolic acidosis, increased anion gap, ketosis and a preliminary diagnosis of DKA. Further investigation revealed IVA. This case is of interest because of the rarity of this presentation and detection of a splicing mutation in the isovaleryl-CoA dehydrogenase gene.
