Well-defined mass in the right pectoralis muscle deep to the breast tissue showing the rapid, washout enhancement seen in malignant lesions. B-value of 1000 showing restricted diffusion.
Well-defined hypoechoic mass in the pectoralis muscle. It was biopsed after careful consideration of surgical planning in consultation with the surgeon.

Well-defined mass with washout enhancement and restricted diffusion in the pectoralis muscle, not the breast parenchyma. Biopsy suggests a low-grade sarcomatous lesion with associated chronic inflammation.
