CT-guided stereotactic biopsy (STB) is a safe and effective neurosurgical tool for diagnosing intrinsic brain masses unsuitable for surgery. It aids in treating gliomas and specific lesions like brain stem masses, lymphomas, and inflammatory conditions.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Neuropathology

Background:

  • CT-guided stereotactic biopsy (STB) has a long-established safety and efficacy record since the 1980s.
  • STB is crucial for diagnosing intrinsic brain masses not amenable to surgical excision due to location, histology, or multiplicity.

Purpose of the Study:

  • To highlight the diagnostic and therapeutic utility of stereotactic biopsy in neurosurgery.
  • To emphasize STB's role in managing specific brain pathologies.

Main Methods:

  • Utilizes computed tomography (CT) guidance for precise instrument navigation.
  • Employs stereotactic techniques for accurate tissue sampling of brain lesions.

Main Results:

  • STB is effective for diagnosing intrinsic brain masses unsuitable for radical excision.

  • It serves as an initial treatment modality for low and high-grade gliomas when combined with adjuvant therapy.
  • STB is the preferred method for determining the histology of brain stem masses in children and adults, as well as specific lesions like pineal germinomas, cerebral lymphomas, AIDS-related brain masses, and inflammatory masses.

    • Conclusions:

    • Stereotactic biopsy is an indispensable tool in neurosurgical practice.
    • STB offers a minimally invasive approach for accurate diagnosis and management of complex brain lesions.
