Multinodular and vacuolating neuronal tumor of the cerebrum (MVNT) is a superficial neuronal tumor in adult that were first documented in 2013 1).


Chen et al described in 2013 an alternate approach involving temporal horn to prepontine cistern shunting followed by radiosurgery of the offending lesion. This 41-year-old woman with a history of meningiomatosis presented with progressive, incapacitating headache. Magnetic resonance imaging (MRI) showed growth of a right trigone meningioma, causing entrapment of the right temporal horn. A ventricular catheter was placed using frame-based stereotaxy and image fusion computed tomography/MRI to connect the entrapped lateral ventricle to the prepontine cistern. The patient reported complete resolution of her symptoms after the procedure.

Postoperative MRI revealed decompression of the temporal horn. The trigonal meningioma was treated with stereotactic radiosurgery. The patient remained asymptomatic at the 2-year follow-up 2).
