Objectives  This study was to demonstrate surgical technique for an anterolateral foramen magnum meningioma. Design  Present study is presented through an operative video. Setting  This study is conducted at the Department of Neurosurgery, Tîrgu Mureș, Romania. Participants  A 62-year-old female is the participant who was diagnosed with a foramen magnum meningioma. Main Outcome Measures  Complete surgical resection of the tumor with no postoperative deficits or complications. Results  A 62 years-old female was admitted for left hemilingual atrophia, dysphonia, right hemiparesis grade 2 of 5, right hemihypesthesia, and cervical pain. The magnetic resonance imaging (MRI) showed a right foramen magnum meningioma, sized approximately 2 cm in all planes ( Fig. 1 ). This was classified with the Bernard system as an intradural foramen magnum meningioma with anterolateral insertion to the dura mater and below the vertebral artery. A suboccipital, retrocondylar, and c1 right hemilaminectomy approach was performed. Using microsurgical tumoral decompression techniques, ultrasonic aspiration, and following the natural cleavage planes, complete tumor removal was achieved ( Fig. 2 ). The patient presented an uneventful postoperative course with no postoperative new neurological deficits and was discharged at home 7 days following surgery. Control MRI at 6 months ( Fig. 1 ) and 2 years showed no tumor residue or recurrence. Neurologic status at 6 months was excellent, showing complete remission of symptoms. Conclusion  Retrocondylar suboccipital approach is a safe and feasible option for anterolateral foramen magnum meningiomas provided that natural corridors and dynamic retraction are used.
