(A). In a woman with newly diagnosed left breast cancer, staging MRI identified a 6 mm indeterminate enhancing mass (yellow arrow) in the right breast located posteriorly close to chest wall. (B). During biopsy small dead space (red asterisks) is always noted close to the chest wall that lies beyond the grid. (C). For biopsy, the introducer was inserted through the posterior most hole in the grid (blue arrow) close to the lesion (yellow arrow). The needle failed to reach the target adequately. A second introducer guide was inserted outside the grid (in the area of red asterisks), close to the chest wall using free-hand direct puncture. (D). The posterior needle (red arrow) was seen to adequately reach the target and biopsy was completed successfully. The histology was reported as lobular neoplasia.
