AbstractA 32-year-old female patient presented with migraine and a bipolar disorder with frontal lobe dysfunction and bilateral pyramidal tract signs on examination. MRI brain revealed confluent bilateral symmetric white matter signal abnormality on T2 and FLAIR images with mild cerebral atrophy. Classic widening of Sylvian fissures and CSF space anterior to temporal lobes was seen. In view of the clinical and radiologic findings suggestive of a leukodystrophy, she was investigated for the same. Her investigations revealed an high level of urinary glutaric acid 857 mmol/mol creatinine (normal <4mmol/mol creatinine) and 3-hydroxyglutaric acid 44 mmol/mol creatinine (normal <1 mmol/mol creatinine) and plasma glutaryl carnitine 1.2 micromol/L; (normal <0.34 micromol/L). This was diagnostic of glutaric aciduria type 1. She was started on L-carnitine with which she showed clinical improvement. Testing for urinary organic acids is important when looking for treatable metabolic disorders (such as glutaric aciduria type I) in patients with leukodystrophy.
