Cerebellar defect associated with Schimke immuno-osseous dysplasia

We report the finding of an absent cerebellar hemisphere and partial absenc e of the cerebellar vermis in a child with dysmorphic features, spondyloepi physeal dysplasia, steroid resistant nephrotic syndrome secondary to focal segmental glomerulosclerosis and T-cell lymphopenia (Schimke immune-osseous dysplasia). These findings have not, to our knowledge, been described befo re and are likely to represent the consequence of a vascular event either i n-utero or in early infancy. Conclusion Cerebral imaging should be performed early in the course of the disease and should be repeated if further neurological events develop.
