Abstract

The authors present a patient who had a large occipital meningocele, which was transformed into an encephalocele after primary closure due to a large skull defect. Thus, the technical importance of classifying patients with occipital meningocele with a large skull defect and a tight dural obliteration is crucial, not to leave a wide dead space with a potential risk of cerebellar herniation. Encephalocele and meningocele are embryological anomalies, which result in intracranial structures herniation due to inborn skull defect. Acquired encephalocele may develop through the same defect with normal cerebellar tissues; since the prognosis of occipital encephalocele may worsen as the size of herniation increases, the patient underwent a modified dural obliteration technique (Cable Suturing Technique) to adjust the size of the dura and to strengthen it to prevent the risk of future herniation followed by cranioplasty and the cerebellar herniation regressed significantly after the procedure.
