Abstract:
Primary extracranial and extraspinal meningiomas are not very common, less than 1% out of meningiomas and with a pathogeny not well defined. Less than 60 cases have been described so far. The histopathological diagnosis can be really difficult. All the cases published were diagnosed after an anatomopathological study. We reviewed all publications about these tumors, which belong to the group of those rare neoplasms the otorhinolaryngologist must have in mind whenever he faces a paranasal sinus neoformation.
Insights
Primary extracranial and extraspinal meningiomas are rare tumors, accounting for less than 1% of all meningiomas. Their exact cause remains unclear, and diagnosis can be challenging, requiring careful histopathological examination.
Area of Science:
- Neuro-oncology
- Pathology
- Otorhinolaryngology
Background:
- Primary extracranial and extraspinal meningiomas are rare neoplasms, constituting less than 1% of all meningiomas.
- The pathogenesis of these tumors is not well understood.
- Fewer than 60 cases have been documented in medical literature.
Observation:
- Histopathological diagnosis of these tumors can be exceptionally difficult.
- All previously reported cases were diagnosed through anatomopathological studies.
- These rare neoplasms should be considered by otorhinolaryngologists when encountering paranasal sinus tumors.
Findings:
- Extracranial and extraspinal meningiomas represent a rare subset of meningiomas.
- The diagnostic process relies heavily on detailed histopathological analysis.
- Literature review indicates a low incidence and poorly defined etiology.
Implications:
- Increased awareness among otorhinolaryngologists is crucial for timely diagnosis.
- Further research into the pathogenesis may improve diagnostic accuracy.
- This review consolidates existing knowledge on these rare tumors for clinical reference.
