CaseHPOFreeText: Frequent episodes of upper airway inflammation, neuro-motor delay, palpable liver, mitral dysplastic valve, thickened and prolapsing flaps with moderate mitral valve insufficiency. MRI of the brain showed dilated perivascular Virchow-Robin spaces, in the peritrigonal site bilaterally and in the corpus callosum, and a slightly dilated ventricular system in the supratentorial area. Slight tibial valgus. X-rays detected an altered coxo-femoral joint with lateralization of the femoral head.

CaseBMT: Yes, UCB-HSCT & MUD-HSCT. First allo- HSCT from unrelated cord-blood-derived stem cells was at the age of 27 months. Six months later (33 months of age), she underwent a second HSCT from an HLA-matched unrelated donor. Normal IDUA activity was reported about 30 days post HSCT and progressively decreasing urinary GAG.
