Insights
A rare intradiploic meningoencephalocele occurred in a child after craniosynostosis surgery due to a dural tear. This case highlights a unique complication following skull surgery.
Area of Science:
- Neurosurgery
- Pediatric Neurosurgery
- Craniofacial Surgery
Background:
- Craniosynostosis repair can rarely lead to complications like growing skull fractures.
- Accidental dural lacerations during surgery are a known risk factor.
Observation:
- A 6-year-old girl developed a right frontal intradiploic meningoencephalocele post-craniosynostosis surgery.
- Symptoms included headache and a palpable frontal mass.
- Imaging revealed an intraosseous cyst with herniated cerebral tissue.
Findings:
- This is the first documented case of an intradiploic meningoencephalocele after craniosynostosis repair.
- The lesion mimicked post-traumatic growing skull fractures.
- Surgical repair with duraplasty and cranioplasty yielded positive outcomes.
Implications:
- This case expands the understanding of potential complications following craniosynostosis surgery.
- It emphasizes the importance of meticulous dural repair.
- Further research into the pathogenesis of intradiploic lesions is warranted.
Abstract:
The authors present the case of a 6-year-old girl who developed a right frontal intradiploic meningoencephalocele following an accidental dural tear produced during surgery for craniosynostosis. Although rare, growing skull fractures have been described in at least eight cases following the accidental laceration of the dura mater in the course of craniosynostosis repair. These cases closely resemble those produced by accidental trauma to the growing skull. However, the intradiploic location of a meningoencephalocele following surgery for craniosynostosis has not been documented previously. This patient presented with headache and a frontal tumor of bonelike consistency. Radiographs and computerized tomography scans of the skull revealed an intraosseous cyst, whereas magnetic resonance imaging demonstrated cerebral tissue herniation within the intradiploic tumor. Surgical treatment consisted of duraplasty and cranioplasty, which achieved good functional and cosmetic results. The pathogenesis of this unusual lesion is discussed and compared with the hypotheses advanced for explaining posttraumatic intradiploic cysts.
