Hajdu-Cheney syndrome (HCS) is an autosomal dominant condition comprising osteolysis of the terminal phalanges, characteristic craniofacial abnormalities, dental anomalies, and proportionate short stature. The clinical and radiological findings develop and progress with age. Here, we report on a HCS patient with severe scoliosis and exceptionally massive dural ectasia. Congenital scoliosis and dural ectasia have not been reported previously in HCS.
