Intraventricular meningioma resection and visual outcomes. J. Neurosurg. (IF 4.1) Pub Date : 2023-09-22 John P Andrews,Daniel D Cummins,Ramin A Morshed,Benyam Kinde,Manish K Aghi,Michael W McDermott,Mitchel S Berger,Philip V Theodosopoulos
OBJECTIVE Intraventricular meningiomas (IVMs) of the lateral ventricle are rare tumors that present surgical challenges because of their deep location. Visual field deficits (VFDs) are one risk associated with these tumors and their treatment. VFDs may be present preoperatively due to the tumor and mass effect (tumor VFDs) or may develop postoperatively due to the surgical approach (surgical VFDs)
