Late closure of the stoma by spreading of a periaqueductal glioma: an unusual failure of endoscopic third ventriculostomy. Case report.


The late failure of endoscopic third ventriculostomies (ETVs) has been described as a consequence of scarring phenomena involving the third ventricular floor. Although the possibility of closure of the stoma by intraventricular tumor seeding has been hypothesized, no case of ETV failure caused by tumor diffusion has been reported in the literature.
