Objectives We present a challenging case of a 61-year-old male patient with a double meningioma. The first one was located on the right side of foramen magnum and the second one was located on left anterolateral side of C1-C2. Background Patient referred at our institution for a progressive spastic paraparesis from approximately 1 year with a recent onset of numbness in right hand. Neuroradiological imaging showed an extra-axial enhancing tumor with a dural tail on the right border of foramen magnum and another contralateral extra-axial enhancing lesion at C1-C2 level ( Fig. 1 ). Results We have chosen a park bench position. Neurophysiological monitoring was used during both positioning and surgery. A linear skin incision in the occipital region extended to C7 was performed and a suboccipital craniotomy with the laminectomy of C1-C3 was performed ( Fig. 2 ). Videofluroangiography was performed to the best visualization of the vertebral artery position during microsurgical dissection and exposure of craniovertebral junction region. An Y -shape dural opening was executed and two meningiomas was resected with the classical four D steps (devascularize, detach, debulking, and dissect). All anatomical structures were respected and there were no changes at neuromonitoring. Patient was discharged after 10 days in good neurological condition. Conclusion a single approach for multiple meningiomas of the craniovertebral junction and upper cervical spine region is feasible and effective. Videofluoroangiography as a way to achieve better visualization and control of the vertebral artery, and neurophysiological monitoring are crucial tools to reduce the morbidity of this surgical challenge.
