Schinzel-Giedion syndrome is a rare multiple congenital malformation syndrome defined by an evocative midfacial retraction, kidney and urinary malformations and multiple skeletal abnormalities associated to a recently described neurodegenerative process. Two children with SGS are reported with identical clinical findings: megacalycosis, progressive neurodegeneration with infantile spasms and hypsarrhymtic activity. Ocular investigations revealed alacrimia and corneal hypoesthesia. Computed tomography of the temporal bone showed a tuning-fork malformation of the stapes for both children. These features may contribute to further delineation of SGS as additional clinical criteria.
