case_images: Conditioning regimen: fludarabine 30 mg/m2/day i.v. over 30 min (total 180 mg/m2). Busulfan 3,2/1,6 mg/kg body weight/d i.v. once daily over 3 h (total dose 8 mg/kg body weight) without busulfan kinetics/targeted AUC. Anti-thymocyte globulin (ATG, Grafalon  Neovii, Switzerland) 30 mg/kg bodyweight/day i.v. over 6-12 h. Methotrexate 15 mg/kg body weight i.v. bolus on day +1 and 10 mg/kg body weight on day +3 and +6.

case_images: In neuropsychological tests performed 2.5 months before allo-HSCT, the patient showed below-average performance (T <= 40) in non-verbal learning and memory, working memory, and processing speed compared with age-, sex-, and education-based norm data and average reaction times in alertness tests [, Figure 2].
case_images: T2 SPACE dark fluid/FLAIR white matter integrity MR images, [18F] florbetaben myelin PET images, and overlaid PET/MR images of both adult-onset leukodystrophy with axonal spheroids and pigmented glia patients, together with (to illustrate respective imaging normality as a comparison) those of a healthy control subject. For the patients, baseline and follow-up images are shown. While in both patients with a favorable symptom outcome long-term after therapy, MRI showed progression of structural white matter integrity and subcortical atrophy, the Myelin PET images (white arrows) remained comparatively stable over time.
