Insights
A rare case of primary meningeal lymphoma presented as a focal mass, mimicking a meningioma. This diffuse lymphocytic lymphoma was confirmed by pathology, with no signs of systemic disease.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Intracranial tumors can present with diverse radiological features.
- Meningiomas are common primary tumors of the meninges.
- Primary meningeal lymphomas are rare and typically diffuse.
Observation:
- A 48-year-old woman presented with an intracranial tumor.
- Radiological imaging suggested a meningioma.
- The tumor was located in the meninges.
Findings:
- Pathology revealed a well-differentiated, diffuse lymphocytic lymphoma.
- No evidence of systemic lymphoma was detected.
- The focal mass presentation is unusual for primary meningeal lymphoma.
Implications:
- This case highlights the importance of considering lymphoma in the differential diagnosis of meningeal tumors.
- Accurate pathological diagnosis is crucial for appropriate treatment planning.
- Understanding rare presentations of meningeal lymphoma can improve diagnostic accuracy.
Abstract:
We describe a 48-year-old woman with an intracranial tumor located in the meninges. Radiologic images were consistent with meningioma. Pathology showed that it was well differentiated and diffuse lymphocytic lymphoma. No evidence of systemic disease was found. Primary meningeal lymphomas generally infiltrate the subarachnoid space in a diffuse way and their presentation as focal and localized masses in unusual.
