A Stepwise Posterolateral Approach for Computed Tomography Guided C2 (Axis) Transpedicular Biopsy: A Technical Note

This paper describes a method for taking a biopsy of the C2 vertebra using a minimally invasive, CT-guided procedure. The posterolateral approach is used to avoid critical structures, and local anesthesia is administered, which is less risky for some patients than general anesthesia. The stepwise approach helps ensure the procedure is performed safely and accurately, leading to high-quality biopsy samples.

• 1
  The study demonstrates that a minimally invasive posterolateral percutaneous CT-guided approach for C2 biopsy is safe and precise.
• 2
  The stepwise approach aids in getting repeatable and high-yielding results in technically challenging areas like C2 vertebrae.
• 3
  The biopsy procedure, lasting 54 minutes, successfully diagnosed moderately differentiated adenocarcinoma from the lung with metastasis to C2 vertebrae.
