Metastatic spread of benign intracranial meningioma
Journal of Neurosurgical Sciences
|January 1, 1987
Abstract:
A case of benign meningioma of the superior sagittal sinus is reported, which recurred three times during a period of six years. At the time of the first recurrence the overlying bone was eroded and the tumor grew subcutaneously; the second recurrence was associated with a pulmonary metastatic deposit of extraordinary size. The literature dealing with remote extracranial spread of meningiomas is briefly reviewed.
Insights
A benign meningioma of the superior sagittal sinus recurred three times over six years. This case highlights rare subcutaneous and pulmonary spread of this typically benign brain tumor.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Meningiomas are typically benign tumors arising from the meninges.
- Superior sagittal sinus meningiomas are a common subtype.
- Recurrence and distant metastasis are rare but documented complications.
Observation:
- A case of benign meningioma involving the superior sagittal sinus is presented.
- The tumor recurred three times over a six-year period.
- The first recurrence involved bone erosion and subcutaneous tumor growth.
Findings:
- The second recurrence was associated with a large pulmonary metastatic deposit.
- This case demonstrates an extraordinary example of remote extracranial spread.
- Review of literature on meningioma extracranial spread is included.
Implications:
- This case underscores the potential for aggressive behavior and distant metastasis even in histologically benign meningiomas.
- Highlights the importance of long-term surveillance for superior sagittal sinus meningiomas.
- Contributes to understanding the rare phenomenon of extracranial spread in meningiomas.
