Summary
Ultrasound-guided core needle biopsy is a safe and accurate method for diagnosing thoracic lesions. A single sample using an 18-gauge needle often provides sufficient histologic diagnosis.
Area of Science:
- Radiology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Thoracic lesions require accurate diagnosis for effective treatment.
- Ultrasound (US) guidance offers a minimally invasive approach for tissue sampling.
Purpose of the Study:
- To evaluate the diagnostic utility and safety of US-guided core needle biopsy for thoracic lesions.
- To determine the optimal needle size and sampling strategy for thoracic lesion biopsy.
Main Methods:
- Retrospective analysis of 45 US-guided core needle biopsies performed between January 1997 and June 2000.
- Biopsies were performed on lesions abutting the chest wall or in the supraclavicular region.
- Histologic examination, including immunohistochemistry, was used for diagnosis.
Main Results:
- A definitive histologic diagnosis was achieved in 95.68% (43/45) of cases.
- The mean lesion diameter was 4.5 cm, with an average of 1.8 passes.
- Minor complications (pain, weakness) occurred in 4 patients; no major complications were reported.
- An 18-gauge needle was used in 41 cases, proving sufficient for diagnosis.
Conclusions:
- US-guided core needle biopsy is a safe, quick, and accurate diagnostic tool for thoracic lesions.
- An 18-gauge needle and a single biopsy sample are often sufficient for achieving a final histologic diagnosis.
- This technique is particularly useful for lesions accessible via the chest wall.
