Psammomatous extra-calvarial meningioma of the neck

Area of Science:

• Neurosurgery
• Oncology
• Head and Neck Surgery

Background:

• Meningiomas are tumors arising from the meninges.
• Primary parapharyngeal space meningiomas are exceptionally rare, with few documented cases.
• Meningiomas typically originate within the cranial vault or spinal canal.

Purpose of the Study:

• To report a unique case of primary parapharyngeal space meningioma.
• To describe the simultaneous presentation of two distinct tumor masses originating from separate cranial nerves.
• To contribute to the limited literature on this rare condition.

Main Methods:

• Case report detailing clinical presentation, diagnostic imaging (MRI/CT), and histopathological findings.
• Surgical management approach for the distinct tumor masses.
• Review of relevant literature on parapharyngeal space meningiomas.

Main Results:

• Successful surgical resection of two distinct meningioma masses.
• Confirmation of primary parapharyngeal origin from separate cranial nerves.
• Absence of recurrence at follow-up.

Conclusions:

• Primary parapharyngeal space meningioma can present as multiple distinct masses.
• Simultaneous origin from separate cranial nerves is an exceedingly rare phenomenon.
• Complete surgical excision is the recommended treatment for such rare presentations.
