Neurochemistry evaluated by MR spectroscopy in a patient with xeroderma pigmentosum group A.

Abstract:

:MRI of a female patient with xeroderma pigmentosum group A (XP-A) showed progressive cerebral atrophy, but no disease-specific lesion. MR spectroscopy with short TE sequences in the bilateral white matter revealed decreased N-acetyl aspartate (neuro-axonal marker) and increased myo-inositol (astroglial marker) with a normal concentration of choline (membrane marker), which are compatible with the neuropathology of XP-A, consisting of a reduced number of neurons, and fibrillary astrogliosis with preservation of myelinated fibers. MR spectroscopy reveals neurochemical derangement in XP-A, which cannot be observed on conventional MRI, and will be useful to monitor the neurochemical derangements of XP-A.
