Intracerebral meningioma with disseminated arachnoidal ossification
Surgical Neurology
|February 1, 1978
Abstract:
A case of intracerebral meningioma associated with disseminated plaques of arachnoidal ossification is presented. The osseous plaques were situated on the same side and predominant in the neighborhood of the tumor. Histologically the ossification was thought to have originated from the wall of the pial vessels.
Insights
This case study presents an intracerebral meningioma linked to widespread arachnoidal ossification plaques. The ossification, primarily near the tumor, likely originated from pial vessel walls.
Area of Science:
- Neuropathology
- Neurosurgery
- Vascular Biology
Background:
- Meningiomas are primary intracranial tumors arising from the meninges.
- Arachnoidal ossification is a rare condition characterized by bone formation within the arachnoid mater.
- The association between meningiomas and arachnoidal ossification is not well-documented.
Observation:
- A case of intracerebral meningioma was identified.
- Disseminated plaques of arachnoidal ossification were observed.
- These osseous plaques were predominantly located on the same side and in the vicinity of the meningioma.
Findings:
- Histological examination suggested the ossification originated from the walls of pial vessels.
- This indicates a potential link between vascular changes and bone formation in the arachnoid.
Implications:
- Understanding this association may offer insights into the pathogenesis of meningiomas and arachnoidal ossification.
- Further research could explore the role of vascular factors in meningioma development.
- This case highlights the importance of considering rare associations in neurosurgical pathology.
