Falcine meningioma: FEBAIR principles in a “Grade Zero” concept application – 2D operative video

Abstract

Background: Falcine meningiomas account for 5% of intracranial meningiomas. They may involve the eloquent cortex as well as vascular structures. Gross-total resection with additional margins has been shown to be beneficial to patients and has been associated with a reduction in disease recurrence. Case Description: A 57-year-old patient presented with recurrent frontal headaches that worsened when lying down. Magnetic resonance imaging showed a large lesion with homogeneous enhancement attached to the anterior third of the falx cerebri at the right frontal lobe, causing significant compression, and suggesting a meningioma. Conclusion: This operative video highlights the application of 1st-time, exposure, bone removal, arachnoid, irrigation, and reconstruction principles for safely and effectively removing a large falcine meningioma using the “grade zero” concept for maximal resection.
