Summary
Preoperative ultrasound-guided charcoal suspension injection successfully localized non-palpable breast lesions (NBPL) in nearly 20% of cases. This sonographic method offers a viable alternative to stereotactic mammography for specific breast abnormalities.
Area of Science:
- Radiology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Non-palpable breast lesions (NBPL) present diagnostic challenges.
- Accurate localization is crucial for effective surgical excision.
- Alternative localization techniques are continuously explored.
Purpose of the Study:
- To evaluate the efficacy of preoperative sonographic localization using charcoal suspension for NBPL.
- To compare sonographic localization with stereotactic mammography.
Main Methods:
- Surgical excision was performed on 253 patients with NBPL between 1987 and 1992.
- Fifty-one lesions were localized via ultrasound-guided injection of sterile 3% charcoal suspension.
- Sonographic features of NBPL were classified.
Main Results:
- Sonographic localization successfully identified 51 (19.7%) of the NBPL.
- Positive sonographic findings were noted in 2% of cases, doubtful in 60%, and negative in 38%.
- The procedure proved useful for breast masses, increased tissue density, or distorted architecture.
Conclusions:
- Preoperative sonographic localization with charcoal suspension is a practical alternative to stereotactic mammography.
- This technique aids in the surgical management of non-palpable breast lesions.
- Sonography provides valuable guidance for specific breast abnormalities requiring excision.
