Spectrum of magnetic resonance imaging findings in a family with giant axonal neuropathy confirmed by genetic studies.
Giant axonal neuropathy (GAN) is a disorder that affects both the peripheral and central nervous system with clinical and genetic heterogeneity. We describe the spectrum of magnetic resonance imaging (MRI), MR-spectroscopy (MRS), and diffusion changes in two siblings from India. In addition to the described MRI findings two unreported findings, hyperintensity signals of both the globus pallidus on T1-weighted images and involvement of bilateral thalamus, were observed. MRS showed elevated choline peaks and reduced N-acetylaspartate peaks as well as presence of lactate peaks. Diffusion weighted images showed restricted diffusion.
