X-linked adrenoleukodystrophy (ALD) is a genetically determined metabolicdisorder that manifests clinically as dysfunctions of the central nervous
system (CNS), adrenal glands, and testicles. These dysfunctions are related
to excessive accumulation of very long chain fatty acid (VLCFA) in tissues
and plasma, which is caused by the failure of oxidative degradation of
VLCFA that normally takes place in peroxisomes.There is widespreaddemyelination of white matter ( particularly bilateral parieto-occipital
region ) with inflammatory reaction and atrophy of adrenal cortex..

Diffuse confluent periventricular

subcortical U fibers,
predominantly in the bilateral
parietal region. Linear hypointense
signals also noted in the white
matter giving tigroid appearance.

Mucopolysaccridosis There is straightening of
the dorsal lordosis. The inferior-most thoracic
and superior-most lumbar vertebral bodies
show an abnormal shape with anterior notches
on either the superior or mid-thirds, as well as
a degree of inferior beaking. The interpedicular
distance is preserved.
