title: Black Hole in the Breast.
abstract: We report an unusual artifact, which was seen on a routine preoperative chest radiograph performed in a patient with breast cancer, before an elective mastectomy. Subsequently, this was identified to be secondary to a preoperative sentinel node injection. The report discusses the diagnostic dilemma caused by this artifact and raises the awareness of this possibility in patients undergoing these commonly performed procedures and investigations.
