Role of MRI in X-linked adrenoleukodystrophy-A case report

X-linked adrenoleukodystrophy is a rare inherited peroxisomal disorder that occurs due to a genetic mutation. This mutation impairs normal transport of very long-chain fatty acids (VLCFAs) into peroxisomes, hence impeding VLCFA breakdown leading to its accumulation in plasma and tissues of the body. Due to its X-linked inheritance, it classically affects young males with most cases diagnosed during childhood. There are characteristic MRI findings in brain which can aid in diagnosis of X-ALD. We hereby present a case of a 10-year-old boy who presented with neurological and behavioral deterioration with MRI findings suggestive of X-ALD. MRI not only aids in diagnosis of X-ALD but can also identify the pattern of brain involvement which serves an important role in prognosis and outcome of the disease.
