A rare inborn error of metabolism masquerading as meningitis

We hereby describe a 7-month-old female baby, born to first-degree cousins, who was initially diagnosed as meningitis based on the features of seizures and dystonia with fever. Detailed review of brain imaging and high urinary 3-hydroxy (3-OH) glutaric acid level confirmed the diagnosis of glutaric aciduria Type I. There is a high probability of these cases getting misdiagnosed as meningitis. Persistent rigidity and dystonia precipitated by a febrile illness and the typical brain imaging picture are clues to the diagnosis of glutaric aciduria Type I, which can be confirmed by raised 3-OH glutaric acid level in body fluids
