Figure 1

Fluorescence-guided surgery using 5-ALA. Left: Standard white-light intraoperative photograph using the operative microscope. Corticectomy has been performed and the tumor is internally debulked. Resection cavity is visualized without clear tumor-brain interface. Right: Red-violet 5-ALA fluorescence is clearly visualized under blue filter within residual tumor. Note this photograph was taken of a malignant glioma. 5-ALA fluorescence in LGG requires confocal microscopy.
