Rare birth defect in which the fetus fails to develop any spinal structures while in the womb. As a result, the head fully develops within the rectal cavity, in which it remains throughout the patient's life. Marked cognitive deficiency is often a side effect due to the lack of oxygen the brain receives during the formative years. No known cure, and no safe surgical method has been found for extracting the head from the patient's rectal cavity.
