CHIARI I MALFORMATION

Neurosurgical Focus, 2001

It is generally agreed that CMI is defined by tonsillar herniation more than 5 mm below the plane of the foramen magnum. The disorder affects children and adults and may be congenital or acquired.

When Virchow's law fails: Crouzon syndrome as a test case for quantitative suture closure–endocranial shape relationships

Journal of Anatomy, EarlyView.
Crouzon syndrome shows preserved intracranial volume but profoundly altered endocranial shape, with disrupted allometric coupling relative to controls. Treating calvarial suture patency as a continuous, age‐adjusted variable reveals strong system‐level covariation with endocranial morphology, effects invisible to conventional categorical suture scoring.
