We report the case of a Japanese boy whose dysmorphic features were consistent 
with those of Shprintzen-Goldberg syndrome. The radiological features were 
characterized by late-onset craniosynostosis, arachnodactyly, undermodeling of 
short tubular bones, mildly undermodeled and slightly bowed long bones, twisted 
ribs and tall vertebral bodies with elongated neural arches. Apart from the 
craniosynostosis, these skeletal changes resembled those of frontometaphyseal 
dysplasia, a well-known craniotubular dysplasia. Shprintzen-Goldberg syndrome 
also shares many clinical features with frontometaphyseal dysplasia.
