Extracranial and intracranial meningiomas
Abstract:
Meningiomas constitute about 18% of primary intracranial tumors, and they are rarely observed in patients under 30 years of age. In this study, we present the case of a 17-year-old patient who was first seen for a right cervical mass. Further investigation revealed that a meningioma of the posterior cranial fossa had invaded the temporal bone, the infratemporal fossa and the right parapharyngeal region and was at the origin of that cervical mass. This intra- and extracranial meningioma was completely resected in two stages with very satisfactory results. We have reviewed the literature pertaining to the extracranial extensions of meningiomas originating in the posterior fossa.
Insights
This study details a rare case of a meningioma in a 17-year-old, highlighting its extensive extracranial invasion. Complete surgical resection was successful, offering valuable insights into posterior fossa meningioma extensions.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Meningiomas are common primary intracranial tumors, typically affecting adults over 30.
- Extracranial extension of posterior fossa meningiomas is exceptionally rare, particularly in pediatric and adolescent populations.
Observation:
- A 17-year-old patient presented with a cervical mass originating from an intra- and extracranial meningioma.
- The tumor, arising from the posterior cranial fossa, demonstrated extensive invasion into the temporal bone, infratemporal fossa, and parapharyngeal region.
Findings:
- Complete two-stage surgical resection of the extensive meningioma was achieved with satisfactory outcomes.
- Literature review confirms the rarity of such extensive extracranial meningioma manifestations from the posterior fossa.
Implications:
- This case expands the understanding of meningioma behavior and potential for aggressive extracranial spread in younger patients.
- Highlights the importance of considering meningioma in the differential diagnosis of complex head and neck masses in adolescents.
- Emphasizes the feasibility of complete resection even in cases with significant extracranial involvement.
