Multiple bladder diverticula in Williams "Elfin-Facies" syndrome.

Twenty-three children with Williams "elfin-facies" syndrome were reviewed. A striking incidence of multiple bladder diverticula was found (8 children of 14 who had voiding cystourethrograms). The diverticula were usually not identifiable on excretory urography. Children generally have a low incidence of bladder diverticula (excluding "Hutch" diverticula), especially multiple diverticula; thus one should strongly consider the diagnosis of Williams syndrome and other connective tissue diseases when multiple bladder diverticula are identified.
