ABSTRACT
BACKGROUND:
X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder attributed to ABCD1 mutations. Case reports with predominant brainstem involvement are rare. CASE PRESENTATION In this study, we reported a plateau male worker of X-ALD characterized by progressive weakness accompanied by gait instability, mild nystagmus, and constipation. After 2 years of onset, a brain Magnetic Resonance Image (MRI) scan showed no abnormality but genetic analysis revealed a heterozygous mutation (c.1534G>A) in the ABCD1 gene. After 7 years of onset, although the patient was given aggressive dietary and symptomatic treatment in the course of the disease, a brain MRI scan showed predominantly brainstem damage, but serum concentrations of very long-chain fatty acids were normal, and he had been bedridden for almost 2 years with severe bladder dysfunction, forcing him to undergo cystostomy. The patient was discharged with improved urinary retention and renal function.CONCLUSIONS:
We reported an X-ALD patient with a novel ABCD1 variation characterized by brainstem damage and retrospectively summarized the clinical manifestation, MRI features, and genetic features of X-ALD patients with brainstem damage.Palabras clave
