Hyperostosis associated with intracranial meningiomas is a well-described entity. Al Mefty and his colleagues reported in a large series that hyperostosis associated with meningiomas is caused in up to 96% of cases by tumor invasion of the bone.7 Radical resection of these meningiomas can be difficult to achieve because bone infiltration can be hard to recognize.2 For this reason, new techniques that make it possible to intraoperatively identify cranial involvement of tumor are welcome. 5-aminolevulinic acid (5-ALA)–guided resection is an emerging technique in neurooncological surgery that has been largely reported to improve the extent of resection and to influence overall survival of patients affected by malignant gliomas. Conversely, the role of fluorescence-guided surgery on meningiomas remains unclear.
