MR images of patients with GA-1. A-C. The pattern of putamen injury in case 6 with a history of seizure and acute encephalopathic crisis is shown. (A) T2 weighted (T2W) MRI. The red arrow indicates extensively hyperintense striatal involvement in T2W MRI. (B) Diffusion weighted images. The red arrow reveals injury with clearly elevated diffusion of the dorsolateral putamen on diffusion weighted images. (C) Apparent diffusion coefficient map. The image shows minimal restricted diffusion affecting the bilateral putamen. (D) Illustration of imaging of the central auditory pathway. An oblique coronal section onT2WI MRI of case 3 shows the hypointense white matter tract. Letters (a) to (e) denote the apparatus of the auditory pathway. (a) Auditory cortex, (b) Thalamus (medial geniculate body), (c) Midbrain (inferior colliculus), (d) Pons (superior olivary nucleus), (e) Cochlea. Note that no space occupying lesion was noted along the tracts
