Abstract:
Meningiomas without dural connection are rare lesions and often referred to as ectopic. Primary ectopic intraosseous meningiomas are uncommon, accounting for less than 2% of all meningiomas. Herein the authors describe a case of meningioma involving the frontal bone in a 43-year-old man and review the relevant literature.
Insights
Primary ectopic intraosseous meningiomas are rare, accounting for less than 2% of all meningiomas. This case study details a frontal bone meningioma, offering insights into these unusual tumors.
Area of Science:
- Neuro-oncology
- Skeletal oncology
Background:
- Meningiomas typically arise from the meninges, with dural attachment being a common characteristic.
- Ectopic meningiomas, particularly primary intraosseous variants, represent a rare subset of these tumors.
Observation:
- A case of a 43-year-old male with a meningioma involving the frontal bone is presented.
- This lesion lacked dural connection, classifying it as an ectopic intraosseous meningioma.
Findings:
- Primary ectopic intraosseous meningiomas are exceptionally uncommon, constituting less than 2% of all meningiomas.
- The frontal bone location is a rare presentation for this specific subtype of meningioma.
Implications:
- Understanding the distinct origins and behavior of ectopic meningiomas is crucial for accurate diagnosis.
- This case contributes to the limited literature on intraosseous meningiomas, aiding in the characterization of rare cranial bone tumors.
