Radioguided localisation of impalpable breast lesions using 99m-Technetium macroaggregated albumin: Lessons learnt during introduction of a new technique to guide preoperative localisation.

Introduction: Preoperative wire-guided localisation (WGL) of impalpable breast lesions is widely used but can be technically difficult. Risks include wire migration, inaccurate placement, and inadequate surgical margins. Research shows that radioguided occult lesion localisation (ROLL) is quicker, easier, and can improve surgical and cosmetic outcomes.

Peri-implant galactocele following vacuum-assisted core biopsy of the breast: a cautionary tale.

A lactating woman in her early 40s with a strong family history of breast cancer presented with a markedly swollen breast days after having a vacuum-assisted core biopsy performed to sample indeterminate microcalcifications in her left breast. Ultrasound showed a large peri-implant fluid collection which yielded milky fluid on aspiration consistent with galactocele formation. Histology of the core specimens revealed a fragment of fibrous capsule suggesting that the core biopsy had created a fistula between the breast tissue and the peri-implant space.
