Summary
A rare case of atypical meningioma metastasizing to the liver is presented. This study analyzes pathological and immunohistochemical findings to improve understanding of rare meningioma (brain tumor) presentations.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Extracranial metastases from atypical meningioma are uncommon, with liver involvement being exceptionally rare.
- Atypical meningiomas are a subtype of primary brain tumors with a higher risk of recurrence and metastasis compared to typical meningiomas.
Observation:
- A 55-year-old patient with a history of atypical meningioma underwent two surgical resections.
- A liver metastasis from the atypical meningioma was diagnosed four years after the second surgery.
Findings:
- Cytological, pathological, and immunohistochemical analyses were performed on the metastatic meningioma.
- Detailed assessment of the metastatic lesion provides insights into the behavior of atypical meningiomas.
Implications:
- Enhanced understanding of meningioma subtypes and metastatic patterns can aid surgeons in managing complex cases.
- This case highlights the importance of considering rare metastatic sites for atypical meningiomas.
- Pathological and immunohistochemical findings can guide clinical decision-making for rare tumor presentations.
