Clinical diagnosis, biochemical findings and MRI spectrum of peroxisomal disorders.

[x-linked adrenoleukodystrophy]

Peroxisomal disorders are an important group of neurometabolic diseases. The clinical presentation is varied in terms of age of onset, severity, and different neurological symptoms. The clinical course spans from death in infancy, rapid functional decline, slow decline on long-term followup, to apparent stable course. Leukoencephalopathy and developmental anomalies are characteristic findings on cerebral MR imaging. From a diagnostic point of view the disorders can be clinically subdivided into four broad categories: (1) the Zellweger spectrum disorders and the peroxisomal ß-oxidation disorders, (2) the rhizomelic chondrodysplasia punctata spectrum disorders, (3) the X-linked adrenoleukodystrophy/adrenomyeloneuropathy complex and (4) the remaining disorders. This article discusses the role of MRI findings in the clinical approach of peroxisomal disorders with neurological disease.
