An unusual complication occurred during breast cancer surgery when a localization wire migrated to the pleural cavity. This case highlights a rare risk associated with ultrasound-guided wire localization procedures.
Area of Science:
- Radiology
- Surgical Oncology
- Thoracic Surgery
Background:
- Ultrasound-guided wire localization is a standard technique for non-palpable breast lesions.
- This method offers advantages such as reduced operative time and minimal tissue injury.
Purpose of the Study:
- To report a rare case of ectopic breast localization wire migration.
- To discuss the management and implications of this complication.
Main Methods:
- Case report of a 47-year-old female with a history of breast cancer.
- Intraoperative identification of the misplaced wire using X-ray and CT imaging.
- Surgical removal of the wire under thoracoscopic guidance.
Main Results:
- An ultrasound-guided localization wire migrated to the pleural cavity.
- The wire was successfully identified and removed thoracoscopically.
- The patient experienced an uneventful recovery.
Conclusions:
- Ectopic migration of localization wires is a rare but possible complication.
- Multimodal imaging and minimally invasive techniques can effectively manage such events.
- This case represents the first reported instance of wire migration to the pleural cavity in English literature.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
