Summary
A rare intraparenchymal meningioma was diagnosed in a woman presenting with severe headache. Surgical removal confirmed the diagnosis, highlighting this unusual brain tumor presentation.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Intraparenchymal meningiomas are rare primary brain tumors, distinct from their typical dural origin.
- Accurate preoperative diagnosis can be challenging due to overlapping imaging features with other intra-axial lesions.
Observation:
- A 54-year-old woman presented with severe headache and neuroimaging revealed an enhancing intra-axial mass in the right superior temporal region.
- Significant peritumoral edema was noted, initially leading to a preliminary diagnosis of cerebral metastasis.
Findings:
- Surgical resection of the mass was performed.
- Histopathology and immunohistochemistry confirmed the diagnosis of an intraparenchymal meningioma, a rare entity.
Implications:
- This case underscores the importance of considering rare diagnoses in the differential for intra-axial brain tumors.
- Further review of the literature is warranted to understand the pathogenesis and optimal management of intraparenchymal meningiomas.
