Occipital horn asymmetry in children.

In 75 young neurological patients ranging in age from 5 months to nearly 18 years, the left occipital horn was longer than the right in 29 instances whereas the right was longer than the left in only 13 cases (p < 0.025). Elongations of the right occipital horn as well as symmetrical horns were associated with cerebral damage incurred prior to the end of the first year of life (p = 0.06).
