Echogenicity of colorectal metastases to the liver has been shown to correlate with prognosis. While there have been many studies looking at the echogenicity of breast cancer, there has been no study relating the issue of echogenicity to prognosis of breast cancer. In this study, we found that hyperechoic and mixed echogenicity breast cancers are rare compared to hypoechoic breast cancers. There was, however, no difference in the groups with respect to histological size, grade, axillary metastases, hormone receptor status and lymphovascular invasion.

Ultrasound Examination of Skin, Fasciae and Subcutaneous Tissue: Optimizing Rehabilitation for Secondary Upper Limb Lymphedema.

Background: Lymphedema represents a frequent cause of disability for patients undergoing oncological treatments and, being a chronic, non-reversible pathology, requires targeted and continuous rehabilitation treatments. To date, the studies available on the use of ultrasound in patients with lymphedema mainly report descriptive data; therefore, with this study, we wanted to describe in a more objective way the typical ultrasound alterations found in these patients, measuring the thickness of the different superficial structures, and defining subcutis echogenicity.
Methods: 14 patients affected by secondary lymphedema of the upper limbs were enrolled in this cross-sectional observational study (12 had breast cancer and 2 with melanoma as their primary diagnosis).

Purpose: To determine how often non-mass lesions are seen in screening breast ultrasounds, and analyze their ultrasound features according to the ultrasound lexicon to find features suggestive of malignant non-mass lesions.
Methods: This study is a single center retrospective study for nonmass lesions on screening breast ultrasound. Among 21,604 patients who underwent screening breast US, there were 279 patients with nonmass lesions.

Background Breast nonmass lesions (NMLs) are observed at screening and diagnostic US. However, knowledge is limited on imaging features of NMLs at screening US. Purpose To identify features of NMLs at screening US that are suspicious for malignancy based on mammographic findings.

Introduction: Breast pseudoaneurysm is a rare complication following breast interventional procedures such as core biopsies and vacuum-assisted biopsies. The occurrence of pseudoaneurysm increases with the conditions of increased breast vascularity like cancer, pregnancy and lactation.
Case Report: We present two cases of pseudoaneurysm formation secondary to core biopsies of the breasts.
