Scout In, Scout Out: Savi Scout Reflector Traversing A Dilated Duct to the Nipple in Breast Cancer Localisation - A Case Report

Abstract

Abstract
Introduction:
Savi scout system is being widely used for localising and excising breast tumours. While the migration of scout reflectors has been documented, this is the first case of a Savi Scout reflector migrating through a dilated duct near the lesion and coming out of the nipple.

Case Presentation:
A 56-year-old postmenopausal woman with a history of right breast intraductal papilloma which transformed to Grade II Invasive Ductal Carcinoma (IDC) has a Savi Scout reflector placed in the tumour. However, it migrated through a dilated duct and emerged at the nipple, causing severe pain. The reflector was then surgically removed, and the patient subsequently underwent wide local excision with skin marker localisation.

Conclusion:
Anatomical variations such as presence of dilated ducts need to be considered before placing scout reflectors. Appropriate positioning would prevent them from migrating through such ducts avoiding patient discomfort and further procedures for localisation.
