BACKGROUND: Intraventricular meningiomas are uncommon and gross total resection is the recommended treatment. However, total resection may not always be possible, especially in locations in which the lesions are adherent to veins and neural structures. We share our experience with intraventricular meningiomas, focusing on the management strategies and outcomes.
PATIENTS AND METHODS: We describe the data of 7 patients with intraventricular meningiomas operated at our institute over the last 9 years. Three patients had a third ventricular tumor of which two had lesions straddling across the foramen of Monro. The remaining 4 patients had trigonal mass. The clinico-radiological features, management strategies and outcomes have been elaborated with a mean follow-up of 57 months.
RESULTS: The common clinical presentations were raised intracranial pressure symptoms, visual field defects and memory deficits. One patient had multiple meningiomas. Total excision was achieved in all except in 2 patients in whom the lesion straddled across the foramen of Monro with dense adhesions to veins and neural structures. Staged resection was required in one patient with a large trigonal mass. All patients had a low-grade lesion. The tumor recurred in one patient (post-pregnancy) after partial resection. All the patients improved neurologically, and none had added deficits.
CONCLUSIONS: Gross total resection of intraventricular meningiomas although desirable may not be possible in certain cases in which the risks outweigh the benefits. These tumors often are of low histological grade and the treatment strategies should be individualized. Regular follow-up is warranted as these tumors may recur despite a low histological grade.
