Hajdu-Cheney syndrome: report of a family and a short literature review.

We report three members of an Armenian family with Hajdu-Cheney syndrome. The history suggested that five other members of the family were also probably affected. This disorder is important for the radiologist because distinctive radiographic findings make the diagnosis possible before clinical signs and symptoms are fully developed. Additionally, radiographic examination is essential in all patients suspected of Hajdu-Cheney syndrome for confirmation of the clinical diagnosis. Radiographic examination also detects complications of the syndrome not evident on clinical examination.
