Background:
Intraventricular meningiomas constitute 2% of intracranial meningiomas, representing a challenging disease for neurosurgeons; we report our experience through a case series, emphasizing surgical approaches and results.
Methods:
Between 2009 and 2012, four patients underwent microsurgical resection in our department. Clinical and imaging findings, surgical approaches, outcomes, and follow-up were analyzed.
Results:
Four patients (three females and one male) were included and the signs of intracranial hypertension were the main clinical presentation in all cases. The parietal approach through intraparietal sulcus was performed in 3 cases and parieto-occipital interhemispheric surgical route in 1 case. Gross total resection was achieved in all the patients without additional deficits and without the aid of neuronavigation, intraoperative monitoring, and intraoperative magnetic resonance imaging.
Conclusion:
Gross total resection is the gold standard treatment for such tumors and the intraparietal sulcus approach is an excellent choice for most of the cases. Careful anatomical knowledge contributes to a safer procedure even in the absence of high tech equipment assistance.
Insights
This study highlights microsurgical resection for intraventricular meningiomas. Gross total resection was achieved in all cases, demonstrating the efficacy of surgical approaches like the intraparietal sulcus route.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Intraventricular meningiomas are rare, accounting for 2% of intracranial meningiomas.
- These tumors present significant surgical challenges for neurosurgeons.
Purpose of the Study:
- To report surgical experience with intraventricular meningiomas.
- To emphasize surgical approaches and outcomes in a case series.
Main Methods:
- Retrospective analysis of four patients undergoing microsurgical resection between 2009 and 2012.
- Evaluation of clinical and imaging findings, surgical routes, and patient outcomes.
Main Results:
- All four patients presented with signs of intracranial hypertension.
- Gross total resection was achieved in all cases without neurological deficits.
- The intraparietal sulcus approach was used in three cases, and a parieto-occipital interhemispheric route in one.
Conclusions:
- Gross total resection is the standard treatment for intraventricular meningiomas.
- The intraparietal sulcus approach is a viable and effective surgical option.
- Surgical success can be achieved with thorough anatomical knowledge, even without advanced technology.
