title: Lipomas in the corpus callosum and the forehead, associated with a frontal bone defect.
abstract: This report concerns a case of lipomas in the corpus callosum, possibly both lateral ventricles, and the forehead, which were associated with a defect in the frontal bone. It is thought that the lipoma originated in the interhemispheric fissure and extended to the forehead by at least the second month of gestation. It interfered with the development of the corpus callosum, and the collagenous capsule of the lipoma remained till birth. It caused a defect in the frontal bone in the midline, in spite of the development of both frontal bones.
