Summary
Primary intraosseous meningiomas are rare skull tumors often misdiagnosed. Surgical excision and reconstruction are the recommended treatments for these benign bone lesions.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Primary intraosseous meningiomas are rare skull tumors.
- They are often misdiagnosed as primary bone tumors preoperatively.
Observation:
- A unique case of intraosseous meningioma without dural connection is presented.
- This lesion was initially misdiagnosed as Paget's disease and treated conservatively.
- Biopsy revealed a benign, ossified, psammomatous meningioma.
Findings:
- A literature review identified 35 additional cases, totaling 36 patients.
- The mean age at diagnosis was 45 years, with a 2:1 female predominance.
- Most lesions were associated with cranial sutures, and 64% appeared hyperostotic on X-rays.
Implications:
- Intraosseous meningiomas require accurate preoperative diagnosis.
- Wide surgical resection followed by cranial reconstruction is the treatment of choice.
- Further research into the pathogenesis and optimal management of these rare tumors is warranted.
