Overcoming Adversity: Triumph in Managing Recurrent Grade 1 Parasagittal Meningioma Metastasized to the Lung with Surgical Precision and Radiosurgical Resolution. Case Report

This is the authors' abstract. We don't add key points for this paper.

Meningiomas stand as the predominant intracranial tumors, with surgical excision being the gold standard treatment.For inoperable or recurrent cases, radiosurgery emerges as a viable option.The amalgamation of surgical and radiosurgical approaches is gaining traction in treatment paradigms.While extracranial metastasis in benign meningiomas is exceedingly rare, we present the case of a 62-year-old woman manifesting multiple lung masses five years post-complete resection of a benign parasagittal meningioma.Subsequent wedge lung excision unveiled a surprising diagnosis of meningioma.Six months thereafter, magnetic resonance imaging of the brain unveiled two small recurrent parasagittal meningiomas, promptly addressed via Cyberknife radiosurgery with a single fraction of 14 Gy.Astonishingly, complete tumor disappearance was observed at the 12-month follow-up.This report underscores a dual rarity-benign meningioma metastasis and complete tumor regression post-radiosurgery at the 12-month mark.
