Combined supracerebellar infratentorial and right occipital interhemispheric approach to falcotentorial junction meningioma: A case report

BACKGROUND: Falcotentorial meningioma is a rare tumor of pineal region, arising from the dural folds where the tentorium and falx meet. Due to the deep location and near closeness to significant neurovascular structures, gross-total tumor resection in this area can be complicated. Pineal meningiomas can be resected using a variety of approaches; however, all these approaches are associated with a significant risk of postoperative complications. CASE DESCRIPTION: A 50-year-old female patient who presented with several headaches and visual field defect and diagnosed with pineal region tumor is discussed in the case report. Patient was successfully managed surgically by combined supracerebellar infratentorial and right occipital interhemispheric approach. Cerebrospinal fluid circulation was restored after surgery and neurological defects were regressed. CONCLUSION: Our case shows that it is possible to completely remove giant falcotentorial meningiomas with minimal brain retraction, preserve the straight sinus and vein of Galen, and prevent neurological impairments by combining two approaches.
