Lateral ventricular meningiomas are rare tumours that pose considerable surgical challenge. This study attempts to analyse some of the important clinical features of these tumours and review technical considerations in surgery for lateral ventricular meningiomas. A retrospective analysis of the case records of patients with lateral ventricular meningiomas operated in our institute since 1998 with a minimum of one year follow up was done. ⋯ At last follow-up for 10 patients were in GOS 5, two were in GOS 4 and three in GOS 3. Lateral ventricular meningiomas are difficult tumours to operate. Total surgical excision through a superior parietal lobule or middle temporal gyrus approach is possible in most cases with minimal morbidity.

Various transpetrosal approaches have been described for excision of lesions extending into both the middle fossa and the upper petroclival region. These approaches may be associated with significant morbidity. Six patients with lesions along the medial part of the middle fossa and the upper petroclival region were operated by the trans-sylvian transtentorial approach. ⋯ All patients improved clinically after the surgery. There was no procedure related morbidity. The transsylvian transtentorial approach provides adequate access to upper petroclival lesions allowing the tumours in this region to be removed without the need for a petrosal resection.
