Methodology of stereotactic biopsy.

Area of Science:

• Neurosurgery
• Neuroradiology
• Oncology

Background:

• Technological advancements in neurosurgical tools and neuroradiological imaging have increased the use of stereotactic techniques.
• Stereotactic techniques are essential for diagnosing and treating small or deep-seated intracranial expanding lesions.
• These methods are crucial for lesions inaccessible to conventional neurosurgical approaches.

Purpose of the Study:

• To describe common systems and methodologies for stereotactic biopsy.
• To highlight the importance of serial explorations in stereotactic biopsy.
• To emphasize the role of stereotactic biopsy in evaluating tumor characteristics.

Main Methods:

• Review of common stereotactic systems and biopsy methodologies.
• Description of diagnostic procedures for intracranial lesions.
• Emphasis on serial imaging and sampling techniques.

Main Results:

• Stereotactic techniques are widely adopted due to technological improvements.
• Stereotactic biopsy allows for the diagnosis and treatment of challenging intracranial lesions.
• Serial explorations reveal tumor heterogeneity and adjacent brain infiltration.

Conclusions:

• Stereotactic biopsy is a key technique for managing small or deep intracranial lesions.
• Serial sampling during stereotactic biopsy is critical for comprehensive tumor assessment.
• Understanding tumor heterogeneity and infiltration is vital for effective treatment planning.
