Encephalocele, occipital

DA: 147

Developmental anomaly information

Definition: Occipital encephalocele is the most common form of encephalocele in the Western Hemisphere (71% in the United States). Type III of Chiari malformation(CMlll), the most serious form of CM, occurs when the cerebellum and brainstem protrude through the foramen magnum and into the spinal canal. Although rare, the protruding tissue sometimes causes a pouch-like structure to appear on the back of the head or neck (occipital encephalocele). The covering of the brain and spinal cord also can protrude through an abnormal opening in the back of the skull, resulting in significant neurological problems, and life-threatening complications may develop.
