Brain and spinal MR imaging findings in mucopolysaccharidoses: a review
1First Department of Paediatrics, Aristotle University of Thessaloniki, Thessaloniki, Greece. jeff@med.auth.gr
Abstract:
MPS represents a group of rare hereditary disorders characterized by multisystem involvement due to intralysosomal GAG accumulation. Among various tissues, both the central and peripheral nervous system are affected in almost all types of the disease. Thus, brain and spinal MR imaging are valuable tools for the assessment of neurologic involvement, and there is evidence that they might be reliable markers demonstrating disease severity and efficacy of treatment options currently used in patients with MPS. We aimed to review the most prominent MR imaging features of patients with MPS, paying attention to the physiopathologic mechanisms responsible for these alterations. Along with the description of neuroimaging findings, existing data in relation to their correlation with the severity of neurologic involvement is discussed, while another topic of great importance is the effect of various therapeutic regimens in the progression of brain and spinal MR imaging alterations. Finally, recent data concerning MR spectroscopy studies in MPS are also critically discussed.
Insights
Mucopolysaccharidoses (MPS) are rare genetic disorders affecting the nervous system. Brain and spinal MR imaging are crucial for assessing MPS neurological involvement, severity, and treatment effectiveness.
Area of Science:
- Neurology
- Radiology
- Genetics
Background:
- Mucopolysaccharidoses (MPS) are rare hereditary disorders causing multisystemic GAG accumulation.
- Neurological involvement, affecting both central and peripheral nervous systems, is nearly universal in MPS patients.
Purpose of the Study:
- To review prominent MR imaging features in MPS patients.
- To correlate neuroimaging findings with disease severity and therapeutic interventions.
- To discuss MR spectroscopy data in MPS.
Main Methods:
- Literature review of MR imaging and spectroscopy studies in MPS.
- Analysis of neuroimaging findings and their physiopathologic basis.
- Evaluation of treatment effects on MR imaging alterations.
Main Results:
- MR imaging demonstrates characteristic alterations in the brain and spinal cord of MPS patients.
- These imaging findings correlate with neurological involvement severity.
- Therapeutic regimens can influence the progression of MR imaging changes.
Conclusions:
- MR imaging is a valuable tool for assessing neurological involvement in MPS.
- Neuroimaging can serve as a marker for disease severity and treatment efficacy.
- Further research into MR spectroscopy in MPS is warranted.

Glycosaminoglycans
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.
