Visualizing protoporphyrin IX formation in the dura tail of meningiomas by mass spectrometry imaging

ConclusionMALDI-MS/MS visualized a selective accumulation of PpIX within the tumor tissue including the dura tail. Thus, absence of fluorescence in the dura tail as visualized by the operating microscope is not caused by the lack of PpIX formation.
