Interventional magnetic resonance imaging guided aspiration and biopsy of a cystic midbrain tumor

Abstract

Interventional magnetic resonance imaging defines the intraoperative application of magnetic resonance imaging technology, permitting the surgeon to work in an open magnetic field. The application of this technology to pediatric neurosurgery allows precise intraoperative localization of pathology, real-time assessment of the anatomical consequences of surgical and anesthetic interventions, accountability of brain shifts, confirmation of the exact site of biopsy or completeness of lesion removal, and immediate identification of some intraoperative and early postoperative complications. We present the case of a young boy with a cystic left midbrain tumor who underwent interventional magnetic resonance imaging guided aspiration and biopsy to illustrate the surgical advantages of this technology.
