This patient had been treating for a left breast cancer and, on her follow up CT, a left anterior intercostal massa was noted. The oncologist demanded for an histopathology of this lesion.
We tried first an ultrasound-guided approach, but the lesion was not well defined in this imaging modality. So we opted for a CT-guided biopsy.
For a safe approach avoiding lung or heart, the core needle was introduced in a right paramedian point, with a low angle with chest wall, in a way that it would do a long subcutaneous path using sternal edge to support and guide it.
The pathological examination confirmed a breast cancer metastasis.
