Stereotactic needle placement was performed for a mammographically-detected irregular, lobulated lesion of the left breast. In the craniocaudal view (medial to the left), the lesion is predominantly to the medial side of the needle shaft.

The orientation of the needle in relation to the mass is shown. The orthogonal X-ray views allow the surgeon to visualize the location of the mass and plan the excision margins. In this patient, the puncture site was directly over the lesion. 

Occasionally, a lesion in a difficult location dictates placement of the needle through a puncture site remote from the pathology. In that case, the incision may need to be placed close to the lesion, away from the shaft of the needle in order to avoid a long tunnel and inconvenient incision location. The hub of the needle is unscrewed, the needle is backed out through the puncture site and the wire is removed antegrade through the incision with the specimen.
