Craniovertebral junction neoplasms in the pediatric population

Area of Science:

• Pediatric oncology
• Neurosurgery
• Radiology

Background:

• Tumors at the craniovertebral junction (CVJ) are uncommon in children.
• The diverse nature of these rare tumors necessitates ongoing research to define optimal therapeutic strategies.

Purpose of the Study:

• To analyze the characteristics, clinical presentation, and management of pediatric CVJ tumors.
• To present institutional experience with a range of osseous and neural extramedullary neoplasms.

Main Methods:

• Retrospective review of 38 pediatric patients with CVJ tumors diagnosed between 1991 and 2006.
• Utilized magnetic resonance imaging (MRI), computed tomography (CT), 3D CT, and angiography for diagnosis and vascular assessment.
• Interventional radiology techniques such as tumor embolization were employed for specific tumor types.

Main Results:

• Common tumor types included chordoma, fibrous dysplasia, aneurysmal bone cysts, eosinophilic granuloma, Ewing's sarcoma, osteoblastoma, neurenteric cysts, meningioma, schwannoma, and plexiform neurofibromas.
• Predominantly ventral tumor locations were observed, with chordomas frequently associated with hypoglossal nerve palsy.
• Clinical manifestations included head/neck pain (70%), cranial nerve palsies (33%), and swallowing/speech difficulties (28%).

Conclusions:

• Pediatric CVJ tumors present with a wide spectrum of pathologies and clinical symptoms.
• Advanced imaging and interventional techniques play a crucial role in diagnosis and management.
• Understanding tumor-specific presentations, like hypoglossal nerve palsy in chordomas, aids in early diagnosis and treatment planning.
