    A new technique uses flexible needle guides and computerized tomography for intracranial tumor biopsies and cyst aspirations. This minimally invasive approach was successfully demonstrated in three patient cases.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Interventional Radiology

    Background:

    • Intracranial tumor biopsy and cyst/abscess aspiration are critical diagnostic and therapeutic neurosurgical procedures.
    • Traditional methods may involve risks associated with metallic instruments and less precise guidance.
    • Advancements in imaging and instrumentation are needed to improve safety and efficacy.

    Observation:

    • A novel technique employing flexible, non-metallic needle guides was developed.
    • Computerized tomography (CT) served as the primary guidance system for the procedure.
    • The technique was applied to biopsy intracranial tumors and aspirate cysts or abscesses.

    Findings:

    • The described technique enables precise targeting and access to intracranial lesions.

  • Successful application in three distinct cases demonstrates the feasibility and utility of the method.
  • The use of flexible, non-metallic guides potentially reduces risks associated with metallic instruments.

    • Implications:

    • This technique offers a potentially safer and more accurate minimally invasive option for managing intracranial pathologies.
    • It may enhance diagnostic yield and therapeutic outcomes for patients with brain tumors, cysts, and abscesses.
    • Further research could explore broader applications and long-term efficacy of this CT-guided approach.
