Accidental transtumoral microparticle embolization of eloquent brain areas in a case of large temporofrontal meningioma

Interv Neuroradiol. 2008 Sep 30;14(3):339-43. doi: 10.1177/159101990801400317. Epub 2008 Oct 8.


We report a case of transtumoral diapedesis of microparticles during preoperative embolization of a large symptomatic temporofrontal meningioma, resulting in severe neurological deficit. In retrospective analysis of angiographic images, the pattern of supply to the tumour was found to be predictive for wide anastomotic channels connecting the dural and pial supply, thereby increasing the risk of the procedure. Recognising this pattern can prevent this rare cause of complication in a still controversial procedure.
