Publication Comment

The authors present a video of a patient with a craniocervical junction hemangioblastoma which was treated with a far-lateraral retrocondilar approach. During this video the authors clearly exhibit the use of virtual reality to explain the adequate concepts of the surgical strategy. I commend the authors for the good result.

Fig. 1 Preoperative imaging of a craniocervical hemangioblastoma. (A, C) T2-weighted axial and sagittal MRI imaging demonstrates a cystic lesion dorsolateral to the medulla causing medullary compression. (B, D) T1-weighted postcontrast sagittal and axial MRI imaging demonstrates the cystic lesion has a peripherally enhancing mural nodule. MRI, magnetic resonance imaging.

Fig. 2 Three-dimensional modeling and intraoperative images of craniocervical hemangioblastoma. (A) Using virtual reality software, a three-dimensional model of the lesion and associated cerebrovasculature was recreated. (B) intraoperative imaging demonstrates the relationship of anatomic structures to the lesion and the draining vein.
