Gross photographs demonstrating that CHI involves the ventral surface of the cerebellum. a Right and b left lateral views of CHI involving the inferior aspect of the cerebellum in an infant who was 25 weeks gestational age and survived 3 weeks. The left cerebellar hemisphere is partially removed in b to show the depth of involvement by the hematoma. c View of CHI from basal surface of the brain depicted in panels a and b and d an infant who was 25 weeks gestation and survived 3 weeks demonstrate involvement of the ventral surface of the cerebellum. e Close up view of the ventral aspect of the cerebellum from a chronic case of CHI with brown-tinged leptomeninges due to hemosiderin in an infant born at 24.5 weeks gestation and survived 10 weeks. f Superior view of the cerebellum detached from the brainstem showing relative sparing of the superior folia in an infant born at 27.5 weeks gestation and survived 5 weeks.
