Summary
Biopsy techniques guided by CT or ultrasound achieved 92.6% diagnostic accuracy for musculoskeletal lytic lesions. Specialized needles and coaxial systems improved bone penetration for accurate histopathology.
Area of Science:
- Radiology
- Orthopedic Surgery
- Pathology
Background:
- Musculoskeletal lytic lesions require accurate histopathological diagnosis.
- Image-guided biopsy is crucial for tissue sampling.
- Challenges exist in sampling lesions covered by intact bone.
Purpose of the Study:
- To evaluate the diagnostic accuracy of CT and ultrasonographically guided biopsy techniques.
- To assess the efficacy of different biopsy instruments and bone penetration methods.
Main Methods:
- Twenty-eight biopsies (23 CT, 5 ultrasound) of musculoskeletal lytic lesions were performed.
- Biopty techniques (Biopty, Monopty) were used for tissue acquisition.
- Bone penetration was achieved with Ostycut needles and a coaxial system with an eccentric drill.
Main Results:
- Overall histopathological diagnostic accuracy was 92.6% (25/27 cases).
- The coaxial bone biopsy system with an eccentric drill facilitated bone penetration.
- Biopty techniques demonstrated high diagnostic yield for lytic lesions.
Conclusions:
- Image-guided biopsy, particularly using Biopty techniques, is highly accurate for musculoskeletal lytic lesions.
- Advanced tools like eccentric drills enhance bone penetration, improving biopsy success rates.
- Accurate diagnosis of lytic lesions is achievable with minimally invasive image-guided procedures.
