Central nervous system dysmyelination in PIBI(D)S syndrome: a further case

Childs Nerv Syst. 1996 Feb;12(2):110-3. doi: 10.1007/BF00819509.


This is a report of new case of PIBI(D)S, a rare autosomal recessive syndrome characterized by photosensitivity, ichthyosis, brittle sulfur-deficient hair (trichothiodystrophy), impaired intelligence, decreased fertility, and short stature. Bilateral cataract and axial osteosclerosis were also detected. Magnetic resonance imaging (MRI) revealed diffuse central nervous system dysmyelination, a finding also described in the only three other reported cases in which MRI was performed. The paper also considers certain similarities in neurological signs and neuroradiological findings between PIBI(D)S, Cockayne syndrome, and xeroderma pigmentosum--all of which are inherited diseases characterized by photosensitivity and DNA repair defect.
