These chest wall deformities may be associated with upper extremity anomalies.The association of Poland syndrome with either intercostal liver herniation or a spinocerebral deformity has been described, but there is no report of both findings encountered simultaneously.This is the first report of a newborn child with Poland syndrome associated with an intercostal liver segment herniation and thoracic myelomeningocele with features of an Arnold-Chiari II cerebral malformation.
