Dysgenesis of the corpus callosum and hypopituitarism.

A high resolution CT scan demonstrated the unexpected finding of dysgenesis of the corpus callosum in addition to the expected finding of pituitary hypoplasia in three children who presented with growth failure secondary to hypopituitarism. Several of the clinical features reported in association with dysgenesis of the corpus callosum may be ascribed to hypothalamo-pituitary dysfunction. These children emphasize the need to assess the endocrine function of patients with midline structural defects. It should not be assumed that the clinical manifestations are related solely to the anatomical abnormality.
