Summary
Ultrasound-guided wire localization is effective for occult breast lesions, especially when masses are not visible on specimen radiography. This technique aids in confirming complete excision of non-palpable breast abnormalities.
Area of Science:
- Radiology
- Breast Imaging
- Surgical Oncology
Background:
- Occult breast lesions require precise localization for complete surgical excision.
- Preoperative wire localization is a standard technique for non-palpable lesions.
- Ultrasound (US) offers real-time guidance during localization procedures.
Purpose of the Study:
- To evaluate the utility of ultrasound-guided wire localization for occult breast lesions.
- To assess the role of specimen radiography and ultrasound in confirming complete excision.
Main Methods:
- Retrospective review of 1,585 preoperative wire localization procedures from 1990-1992.
- Identification of lesions localized using ultrasound guidance (30 cases).
- Analysis of specimen radiography and post-excision ultrasound findings.
Main Results:
- Out of 1,585 procedures, 739 (47%) involved masses.
- Ultrasound guidance was used for 30 lesions.
- In 5 of 30 US-guided cases, the mass was not visible on specimen radiography.
- Specimen ultrasound confirmed complete excision in these 5 cases.
Conclusions:
- Ultrasound guidance is a valuable tool for localizing occult breast lesions.
- Ultrasound of the specimen can confirm complete excision when radiography is inconclusive.
- This technique enhances the accuracy of surgical removal for impalpable breast abnormalities.
