Peri-Implant Enhancement of the Breast: Imaging Features, Significance, and Management Strategies.

Objective: Peri-implant enhancement can be seen on contrast-enhanced breast MRI, but its association with malignancy has not been described, leading to considerable variability in assessment and recommendations by radiologists. This study evaluated imaging features, management, and outcomes of implant-related enhancement.

Methods: This multisite IRB-approved retrospective review queried all breast MRI reports for keywords describing peri-implant enhancement, fluid, and/or masses (plus synonymous descriptions) and implant-associated malignancies, with subsequent imaging and chart review.

Breast incidentaloma: Cardiac PET readers beware.

Breast cancer remains one of the most common causes of cancer and cancer-related death in women. With increases in medical imaging utilization, incidentally detected cancer has become more prevalent. Specifically, breast cancer can be incidentally detected on nuclear cardiac imaging scans due to its high metabolic activity and because the tumor may fall within the field of view during these studies.

Evaluating acute nipple inversion, imaging findings and outcomes.

Purpose: Acute nipple inversion can be unsettling for patients and is sometimes associated with an underlying breast malignancy. It also poses a diagnostic challenge with lack of consensus management guidelines. This study reviewed institutional experience with new nipple inversion, including malignant association, imaging utilization, and outcomes, in an effort to improve management.

Ultrasound-guided radar reflector localization of axillary lymph nodes facilitates targeted axillary dissection.

Purpose: This study evaluated feasibility and patient outcomes for targeted axillary lymph node (LN) dissection (TAD) with SAVI SCOUT® ultrasound-guided radar reflector localization (RRL).

Methods: In this IRB-approved retrospective study, 800 consecutive patients who underwent ultrasound-guided RRL between November 2017 and June 2020 were reviewed. Of these patients, those with axillary LN RRL were included in this study.

It's Not Always Gynecomastia: A Case of Diffuse Large B-Cell Lymphoma Presenting as Breast Mass in a Male Patient.

We report a case of diffuse large B-cell breast lymphoma that presented as a palpable breast lump in a male patient evaluated with digital mammography and targeted breast ultrasound (US) but ultimately confirmed by US-guided core needle biopsy. We will discuss the appropriate workup algorithm for a palpable breast lump in a male patient as outlined by the American College of Radiology (ACR) Appropriateness Criteria. While gynecomastia is the most common reason for a new palpable breast lump in a male patient, male breast cancer (including lymphoma and metastasis) can have a similar appearance on imaging.

Catamenial Rectus Abdominis Pain Associated with Scar Endometriosis Status-post Low Transverse Cesarean Section.

Endometriosis is the presence of endometrial tissue outside of the uterine cavity. Scar endometriosis (SE), a rare occurrence, results from inadvertent extrapelvic transplantation of endometrial tissue to an incision site, such as from a low transverse cesarean section (LTCS). The reported incidence of abdominal wall scar endometriosis status-post cesarean section is 0.
