      Architectural distortion is present on up to 80% of mammograms at 6 months after ex-cisional biopsy, decreasing to 35% at 2 years. Ultrasound rarely shows frank distortion after benign breast biopsy but can reveal an irregu-lar hypoechoic mass with posterior shadowing. Postlumpectomy.

      Axillary mass or swelling is a common clinical presentation that requires imaging investigation. There is a wide range of differential diagnoses because the axilla contains both lymph nodes and non-lymphatic tissue such as accessory breast tissue, skin, fat, muscles, nerves, blood vessels, and is surrounded by bone.

Splenic lesions are commonly discovered incidentally at imaging, without clinical signs or symptoms that may aid in diagnosis. As such, the differential diagnosis and subsequent management are based primarily on imaging characteristics.
