Age-related metabolic changes in the corpus callosum: assessment with MR spectroscopy.
The aim of this study was to examine metabolite changes in different parts of the corpus callosum (CC), and to relate these changes to different age groups using magnetic resonance spectroscopy (MRS). ⋯ Metabolite ratios in the CC are influenced by age. Age-related changes and regional metabolite levels may cause these alterations. Analyses of the CC may be informative for the evaluation of white matter. MRS may help to demonstrate metabolite levels and ratios of the CC.

ReviewCT and MRI in the evaluation of craniospinal involvement with polyostotic fibrous dysplasia in McCune-Albright syndrome.
In this study, the efficacy of computed tomography (CT) and magnetic resonance imaging (MRI) in the evaluation of craniospinal involvement with polyostotic fibrous dysplasia (PFD) in McCune-Albright syndrome (MAS) and related complications were reviewed. In CT, ground-glass appearance with well-defined borders was seen, with medullary widening and cortical thinning. More rarely, cystic/necrotic areas were observed within involved bone. ⋯ Cystic/necrotic areas were seen as hyperintense images on T2-weighted sequences. While bone marrow involvement was shown more clearly with MRI, compression of cranial and spinal nerves was determined most effectively by evaluation of CT and MRI together. CT and MRI should be employed together in order to demonstrate the extent of disease, and complications of craniospinal involvement of PFD in patients with MAS.

Idiopathic calcification of the intervertebral disc is a rare condition in childhood, of unknown etiology. Calcifications are occasionally discovered on routine radiological examination, or on investigation of nonspecific symptoms such as neck pain, torticollis, fever, and radiculopathy. We report a case of a 7-year-old boy with intervertebral disc calcification. Clinical and radiological signs are discussed.
