T2-weighted magnetic resonance imaging of the brain revealed bilateral frontotemporal atrophy with wide Sylvian fissure giving the "bat-wings" appearance [Figure 1]. Tandem mass spectrometry (MS) revealed increased levels of glutarylcarnitine (1.06 mumol/L; reference range - 0-0.41 mumol/L) and reduced levels of free carnitine (3.99 mumol/L; reference range - 9-65 mumol/L).
