Oblique approach.

A. Localization CT scan of 57-year-old woman with nodular lesion having irregular margins. Anterior end of rib (black arrow) was blocking anterior approach. Alternative approach (black line) is very long and through soft tissue of breast. B. Hence lesion was targeted using oblique approach and minimal lung parenchyma was traversed. Specimen notch is seen in lesion center. C. Sagittal reformatted image demonstrated oblique course of needle from inferior rib margin (arrow) into lesion. Biopsy was suggestive of chronic interstitial fibrosis.
