2025年1月21日 · Loes et al. 10 described five different MRI brain patterns of adrenoleukodystrophy based on the involved anatomic locations and MRI patterns of progression: deep white matter in the parieto-occipital lobes and splenium of the corpus callosum (66% of cases, chiefly in children); may include lesions of the visual and auditory pathways

All neurologically asymptomatic boys with ALD should undergo routine MRI screening for radiographic evidence of CCALD. Boys should begin a surveillance program as early as possible. All MRIs, especially with suspect or confirmed findings, should be reviewed by a physician with expertise in ALD.

Working with your team to monitor for cerebral ALD is a crucial component of your plan. MRI is the earliest opportunity to detect cerebral ALD before any symptoms appear. Detecting cerebral ALD early can have lifesaving results. ALD progresses differently in every child.

MRI signal changes in X-ALD occur due to inflammation and demyelination. The earliest T2 sequence abnormality is thought to be due to myelin membrane instability and oxidative stress that in turn triggers the initial damage that occurs in CALD.

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.

2000年5月1日 · BACKGROUND AND PURPOSE: Early assignment of disease progression among patients with X-linked adrenoleukodystrophy (ALD) is critical for the appropriate selection of effective therapy. We evaluated the association between contrast enhancement on T1-weighted spin-echo MR images and disease progression.

Magnetic resonance imaging (MRI) is the gold standard for the detection of cerebral lesions in X-linked adrenoleukodystrophy (ALD). ALD is one of the most common peroxisomal disorders and is characterized by a defect in degradation of very long chain fatty acids (VLCFA), resulting in accumulation of …

Brain MRI showed posterior cerebrum and brainstem abnormalities consistent with adrenoleukodystrophy 1 (figure). Morning cortisol was decreased (21 nM) and adrenocorticotrophic hormone stimulation test confirmed adrenal insufficiency.

2003年8月12日 · MRI progression in X-ALD depends on patient age, initial MRI Severity Scale score, and anatomic location of the lesion. When used in combination, these data aid the prediction of disease course and the selection of patients for BMT.

Forty-three male patients with X-linked ALD had undergone multiple MR imaging examinations of the brain that consisted of at least sagittal and axial T1-weighted spin-echo, axial double-echo spin-echo, and contrast-enhanced axial T1-weighted spin-echo imaging.
