Abstract:
Rhizomelic chondrodysplasia punctata is a member of genetic peroxisomal disorders. Delayed myelination, which is probably related
to the inadequacy of plasmalogens biosynthesis, is an important feature of this disorder. Direct assessment of neuropathologic aspects of
RCDP syndrome such as neuronal degeneration and delayed myelination is possible with MR spectroscopy.
In this report, MR spectroscopy findings (decreased Cho/Cr and increased Ins-Gly/Cr ratios and increased levels of mobile lipids) of a
rhizomelic chondrodysplasia punctata case supporting delayed myelination are presented. This is the second report of MR spectroscopy
examination of the specific brain metabolic changes associated with rhizomelic chondrodysplasia punctata. © 2003 Elsevier Science Inc.
