A 3-year child is discussed who presented with dyskinesia, large head size, developmental delay, and recurrent infections necessitating multiple hospital admissions. The diagnosis was not made at initial presentation or even after multiple hospital admissions. An organic acidemia was suspected, based on raised ammonia and lactate levels and metabolic acidosis and the diagnosis of glutaric aciduria Type 1 was established by finding markedly elevated levels of glutaric acid and its specific metabolites on urine organic acids analysis by gas chromatography-mass spectrometry, in the setting of specific clinical features. Further supporting evidence was provided by CT scan brain showing subdural hygroma along left cerebral hemisphere causing gyral flattening and widening of sylvian fissure.
