Stereotactic needle biopsy and laser ablation of geographically distinct lesions through a novel magnetic resonance imaging–compatible cranial stereotaxic frame: illustrative case

Abstract

BACKGROUND Current technologies that support stereotactic laser ablation (SLA) of geographically distinct lesions require placement of multiple bolts or time-consuming, intertrajectory adjustments. OBSERVATIONS Two geographically distinct nodular lesions were safely biopsied and laser ablated in a 62-year-old woman with recurrent glioblastoma using the ClearPoint Array frame, a novel magnetic resonance imaging–compatible stereotactic frame designed to support independent parallel trajectories without intertrajectory frame adjustment. LESSONS Here, the authors provide a proof-of-principle case report demonstrating that geographically distinct lesions can be safely biopsied and ablated through parallel trajectories supported by the ClearPoint Array frame without intertrajectory adjustment.
