MRI examples in the different myelopathy diagnostic categories. A, Cervical spine MRI
from a patient with idiopathic inflammatory myelopathy reveals a short-segment lesion
in T2-weighted (T2W) images and T1-weighted gadolinium-enhanced (T1W + Gad) images in
the posterolateral region of the cervical cord. B, Cervical spine MRI from a patient with
spinal cord infarction shows a longitudinally extensive, anterior lesion in T2W images in both
sagittal and axial views, which appears unenhanced in T1W + Gad images. C, Thoracic MRI
in a patient with a dural arteriovenous fistula seen as a longitudinally extensive myelopathy
and diffuse intraaxial enhancement in the central cord; there are enlarged vessels in the
dorsal surface of the cord (arrow). D, Cervical spine MRI in a patient with spondylotic
myelopathy shows posterior disk protrusion with mass effect on the spinal cord and
intraaxial signal abnormality in T2W images and focal enhancement in T1W + Gad images in
the central cervical cord

Т2 и R² карты мышц бедра на МРТ позволяют оценить состояние тканей, выявить воспаления и изменения структуры мышц для ранней диагностики и мониторинга лечения.

Axial HASTE T2-WI at the basal ganglia level showing diffuse homogeneous hyperintense signal in the subcortical white matter with sparing of claustrum and grey matter.

MRS with a single-voxel technique in the parietal lobe showing a prominent doublet peak around 3.7 ppm representing galactitol (arrow).

CLINICAL HISTORY
A 5-week-old male infant of unrelated parents and normal birth presented with progressive enlargement of the head circumference, hypotonia, feeding difficulties with poor weight gain and congenital lamellar cataracts. Later he developed nephrotic syndrome and hypertransaminasemia.

This case proved to be type I galactosemia or “classic” galactosemia phenotype due to nondetectable galactose-1-phosphate uridyltransferase (GALT) caused by mutation of the GALT gene on chromosome 9p13.3 resulting in galactose-1-phosphate and ulterior galactitol accumulation.
Galactosemia is an autosomal recessive inborn error of metabolism with three different types depending on the gene mutation. Symptoms vary depending on the degree of enzyme deficiency/heterogeneity, but children often present with milk-feeding problems with poor weight gain, hypotonia, lethargy, and liver and kidney dysfunction. Accumulation of galactitol in the brain causes cerebral oedema with macrocephaly, while accumulation in the lenses causes cataracts .

Syringomyelia refers to a cystic collection, or syrinx, that occurs within the spinal cord around the central canal. Although syringomyelia is distinct from hydromyelia, in which there is simply dilatation of the central canal, it is very difficult to distinguish the two on imaging. Hence, the collective terms hydrosyringomyelia or syringohydromyelia can also be used to describe this fluid collection within the cord.

Rathke cleft cysts, also known as pars intermedia cysts, are non-neoplastic, sellar or suprasellar epithelium-lined cysts arising from the embryologic remnants of Rathke pouch in the pituitary gland. They are common lesions and usually incidentally identified.

Rett syndrome is a rare neurodegenerative disease seen in young girls in the 2nd to 4th months of life. The majority of cases result from a mutation in the MECP2 gene; a more severe subset of the disease arises from a CDKL5 mutation
