Middle third falcine meningiomas-surgical nuances for cortical venous preservation.

PURPOSE

To improve postoperative outcome in middle third falcine meningiomas by cortical venous preservation.

BACKGROUND

Falcine meningiomas arise from the falx and do not involve the superior sagittal sinus (SSS). Their complete resection is often associated with the risk of venous infarction in the eloquent cortex due to overlying superficial cortical veins on the tumors.

METHOD

We report one case of middle third falcine meningioma, where we used the posterior interhemispheric corridor for tumor approach.

CONCLUSION

Use of the posterior interhemispheric approach, carefully raised bone flap, along with sharp dissection and vein reinforcement using fibrin glue can help to preserve the cortical veins while resecting the falcine meningiomas.
