title: Adrenoleukodystrophy--unusual CT and MR findings in two siblings. Case reports.
abstract: OBJECTIVE
  To describe the unusual appearance of adrenoleukodystrophy (ALD) in MR imaging.
  
  
  METHODS
  An analysis was made of MR findings, histopathology and clinical course in the cases of two brothers with ALD.
  
  
  RESULTS
  The older brother presented with frontal contrast-enhanced lesions, including a cyst. These were initially misinterpreted as a tumour at both radiology and pathology. The correct diagnosis was made after the discovery of very-long-chain fatty acids in the blood. The younger brother presented initially with involvement of various segments of the corticospinal tract.
  
  
  CONCLUSIONS
  It is important that the radiologist be aware of the variants of ALD in MR imaging so as to avoid diagnostic mistakes.
