Pituitary sellar spine in a pediatric patient with diabetes insipidus

A sellar spine is a midline bony spur arising from the ventral aspect of the dorsum sellae. Representing a remnant of the anterior notochord, it is often an incidental finding and thought to be of no clinical significance. However, it has recently been suggested that a potential association may exist between sellar spine and pediatric pituitary endocrinopathies, possibly caused by deformation of the developing pituitary gland by the sellar spine. To our knowledge, this is the first case report demonstrating an association between sellar spine and clinical diabetes insipidus.

Automated summary

A sellar spine is a midline bony spur arising from the ventral aspect of the dorsum sellae, often considered clinically insignificant. Recent research suggests a potential association between sellar spine and pediatric pituitary endocrinopathies, possibly due to deformation of the developing pituitary gland caused by the sellar spine.
