Jarcho-Levin syndrome: unusual survival in a classical case

Spondylothoracic dysostosis, or Jarcho-Levin syndrome, together with spondylocostal dysostosis, constitute a heterogeneous group of rare disorders characterized by short-neck, short-trunk dwarfism and multiple vertebral anomalies at all levels of the vertebral column. The latter include hemivertebrae, fused, hypoplastic, and "butterfly" vertebrae. In most cases of Jarcho-Levin syndrome, the small size of the thorax causes respiratory death in infancy. This report of a Puerto Rican child with spondylothoracic dysostosis and unusually long survival to 11 years exemplifies the nosologic and prognostic difficulties associated with this syndrome.
