Meningiomas of the lateral ventricle. Report on six cases
1Department of Neurosurgery, School of Medicine, Hacettepe University, Ankara, Turkey.
Abstract:
In this study 6 patients who had meningioma of the lateral ventricle are reviewed. The incidence is 1.8% of cases of meningiomas in our series. Microsurgical techniques were employed in all patients. There was no death and the follow-up period was between 5 months and 10 years. No recurrence was seen. Although the origin of these tumors is still not known, DUNN and KERNOHAN note that the choroid plexus has the potential for the production of meningothelial, fibrous, or mixed patterns. Our pathological results confirmed this suggestion.
Insights
This study reviewed 6 lateral ventricle meningioma patients treated with microsurgery. Results showed no deaths or recurrences, supporting the choroid plexus as a potential origin for these tumors.
Area of Science:
- Neurosurgery
- Neuropathology
Background:
- Meningiomas of the lateral ventricle are rare, accounting for 1.8% of meningiomas in this series.
- The exact origin of lateral ventricle meningiomas remains debated.
- The choroid plexus is hypothesized to be a potential origin for these tumors.
Purpose of the Study:
- To review cases of lateral ventricle meningioma.
- To evaluate the efficacy of microsurgical techniques for these tumors.
- To investigate the pathological origin of lateral ventricle meningiomas.
Main Methods:
- Retrospective review of 6 patients with lateral ventricle meningioma.
- All patients underwent microsurgical resection.
- Follow-up ranged from 5 months to 10 years.
Main Results:
- No mortality was observed in the study cohort.
- No tumor recurrence was detected during the follow-up period.
- Pathological findings supported the choroid plexus as a potential origin.
Conclusions:
- Microsurgery is a safe and effective treatment for lateral ventricle meningiomas.
- Long-term follow-up indicates a low recurrence rate.
- Pathological evidence supports the choroid plexus as a likely source for these meningiomas.
