ABSTRACT
Background:
Intraventricular meningiomas are rare tumors and pose clinical, radiological, and surgical challenges. Individualized approach helps to establish successful results.Methods:
Thirteen patients underwent craniotomy for intraventricular meningioma resection from 1999 to 2007. The mean age was 45 years (23-64), time of presentation between 25 days to three years. There were ten females and three males. Headaches and seizures were the most frequent initial presentations. Tumors were located in the ventricular trigone in 11 patients and in the temporal horn in two.Results:
There were seven posterior temporal and seven parieto-occipital transcortical craniotomies, one patient was operated two times. Resection grade was Simpson I in nine patients, Simpson II in four, and Simpson III in one case. Surgical mortality was zero. There were six complications. Two patients had ventriculitis, one patient had hematoma of the surgical bed, one patient had severe post-operative cognitive impairment and one presented with progression of motor deficits. In two patients, there was transient memory disturbance after the parieto-occipital approach.Conclusion:
Correct understanding of microsurgical anatomy cooperates for further success in operation of intraventricular meningiomas. Pre-operative embolization is helpful to reduce bleeding when a suitable tumor feeder can be accessed with no reflux. Dynamic changes in the shape of the ventricular cavity have to be considered when planning the most suitable route. Rigorous hemostasis and ventricular drainage are important points to avoid main complication.
