Clustered Microcysts on Breast Ultrasound: What Is an Appropriate Management Recommendation?

OBJECTIVE: The objective of our study was to determine outcomes of lesions identified as clustered microcysts on breast ultrasound to augment the existing literature and help guide appropriate management recommendations. MATERIALS AND METHODS: We retrospectively identified cases at our institution, from January 2003 through December 2013, of all lesions classified as clustered microcysts at breast ultrasound. Breast ultrasound examinations were performed by the interpreting physician. If ultrasound-guided sampling was performed, results were obtained from the pathology or cytology reports. If sampling was not performed, only lesions with at least 24 months of imaging follow-up or any imaging follow-up with interval resolution or decrease in size were included in the study. Outcomes and frequency of malignancy were determined by reviewing the electronic medical records and our PACS. RESULTS: Of 144 patients with 148 lesions classified as clustered microcysts on ultrasound, 93 patients with 95 lesions had adequate follow-up and were included in our study population. The mean patient age was 50 years (range, 32-72 years). Of the 16 lesions that underwent percutaneous sampling, none (0% [95% CI, 0-21%]) yielded malignancy. Fourteen (88%) sampled lesions were benign, and two (12%) of the sampled lesions revealed atypical ductal hyperplasia at percutaneous sampling but no atypia or upgrade at subsequent surgical excision. In total, 0 of 95 lesions (0% [95% CI, 0-3.8%]) showed malignancy at sampling or imaging follow-up. CONCLUSION: Our results support that lesions sonographically characterized as clustered microcysts carry an extremely low risk of malignancy, and biopsy should be avoided.

Enhancing Your Acoustics: Ultrasound Image Optimization of Breast Lesions.

A general understanding of ultrasound physics relative to image optimization is essential when performing breast ultrasound examinations and in accurately interpreting images of the breast. Appropriate technique is crucial to achieve accurate lesion characterization and is emphasized in the second edition of the American College of Radiology Breast Imaging Reporting and Data System for ultrasound (2013). This pictorial essay reviews clinically relevant ultrasound physics to best characterize breast lesions for guiding the clinician to the proper diagnosis. Differences in chosen parameters on ultrasound imaging can create variability in the appearance of breast lesions.

Surveillance of probably benign (BI-RADS 3) lesions in mammography: what is the right follow-up protocol?

BI-RADS-3 is a category in mammography for probably benign lesions and for which periodic follow-up with repeat imaging is recommended. At our institution repeated mammograms are performed at 6, 12, 18, and 24 months. The purpose of this study was to assess the significance of 18-month mammogram for evaluation of BI-RADS-3 lesions. Following IRB approval, electronic medical records and picture archiving and communications system were used to review 121,862 consecutive mammograms between February, 2002-May, 2009. A total of 8,400 patients with BI-RADS-3 mammograms were identified. Of these, 7,632 patients were followed until completion of 24 month mammogram or biopsy following an upgrade in their BI-RADS status. Over the follow-up, 197 patients received an upgrade in their BI-RADS status of which 179 were biopsied. Histopathologic results were reviewed. The majority of the BI-RADS-3 lesions were upgraded at 6-month mammogram (n = 150, 76.1%) followed by 32 (16.2%), 11 (5.6%), and 4 (2.0%) at 12, 18, and 24 month mammograms respectively. Thirty-four of 179 upgraded and biopsied lesions were found to be malignant. From these 27 (79.4%), 3 (8.8%), 3 (8.8%), and 1 (2.9%) lesions were identified at 6, 12, 18, and 24 month mammograms respectively. At the 18-month mammogram 3/7,632 lesions (0.04%) were found to be malignant. The vast majority of malignant lesions (88.2%) were detected within the first 12-months of follow-up. Only three of 179 biopsies (1.7%) were malignant at 18-month follow-up. Based on those results a 6-, 12-, and 24-month follow-up protocol for BI-RADS-3 lesions is sufficient.

Hiatal hernias.

Esophageal hiatal hernias have been reported to affect anywhere from 10 to 50% of the population. Hiatal hernias are characterized by a protrusion of the stomach into the thoracic cavity through a widening of the right crus of the diaphragm. There are four types of esophageal hiatal hernias: sliding (type I), paraesophageal (type II), and combined (type III), which include elements of types I and II, and giant paraesophageal (type IV). Each type may present with different symptoms and complications. The potential severity of symptoms necessitates proper and prompt diagnosis. Diagnosis is established with the use of barium swallow on chest radiographs. Treatment for sliding hernias involves laparoscopic fundoplication. The aim of our paper is to review the extensive literature regarding hiatal hernias in an effort to enhance awareness and diagnosis of this pathology.

Mass-forming ductal carcinoma in situ: An ultrasonographic and histopathologic correlation study.

Ultrasound (US) guided core needle biopsy (CNB) for mass lesions resulting in a diagnosis of ductal carcinoma in situ (DCIS) is often considered radiologically discordant and generates surgical planning difficulty. One hundred cases of US-guided CNB for mass lesions diagnosed as DCIS were collected from 2013 to 2021. Histological features were reviewed and correlated with radiology and surgical excision findings. Thirty (30%) were high-grade (HG), and seventy (70%) were low- to intermediate-grade. Seventy-one (71%) cases had a histological correlate of a mass-forming lesion, including 26 (26%) were associated with benign mass-forming lesions (category 1) such as papilloma, complex sclerosing lesion/radial scar, fibroadenoma, sclerosing adenosis, and ruptured cyst; 23 (23%) were HG with solid pattern, comedo necrosis, and stromal desmoplasia (category 2); and 22 (22%) had predominantly papillary architecture (category 3). Twenty-nine (29%) were discordant with no histologic correlate of a mass lesion (category 4). Follow-up excisions were available in 79 cases. Invasive carcinoma was identified in 14 cases (18%), of which 8 were from the radiologically discordant category (35%), 3 (17%) associated with HG DCIS with desmoplasia, 2 (10%) associated with benign mass lesion and 1(5%) was predominantly papillary architecture. US-guided CNB for mass-forming lesions with a DCIS diagnosis on CNB can be grouped into four categories. Radiology-pathology correlation is essential. This categorization emphasized rad-path correlation and had a clear difference in upgrade rate on follow-up excision. Rad-path discordant biopsy cases were more likely to be associated with a missed invasive carcinoma (p < 0.05).

Fertility Treatments and Breast Cancer: A Significant Risk for Our Patients?

Fertility medications have been postulated to increase the risk of breast cancer because of the transient but substantial elevation in hormones occurring with their use. Multiple studies exploring the relationship between fertility medications and risk of breast cancer are limited by the wide variety of fertility treatment regimens and confounded by infertility as an independent risk factor for breast cancer. The Practice Committee Guidelines of the American Society of Reproductive Medicine acknowledge that although this relationship is complex, no additional risk of breast cancer has been consistently linked to infertility medications. This article reviews the major studies both supporting and refuting this statement and makes recommendations regarding risk counseling and breast cancer screening in patients with a history of fertility treatments and infertility.

Teaching ultrasound-guided percutaneous breast interventions to a trainee may be a challenge, given the often high-anxiety environment in the subspecialty of breast imaging. This article aims to teach an organized approach, including simulation practice with an emphasis on consistent feedback and role modeling, as well as practical and relevant physics, to help trainees accelerate acquisition of these important skills during their training.

Clinical Breast Magnetic Resonance Imaging: Technique, Indications, and Future Applications.

Breast magnetic resonance imaging (MRI) is the most sensitive imaging modality for the detection of breast cancer, and it is indicated for breast cancer screening in patients at high-risk of developing breast cancer. It is limited to this group given the high cost. In addition, breast MRI is also indicated for evaluating the extent of disease in patients with new breast cancer diagnoses, monitoring the response to neoadjuvant treatment, and evaluating implant integrity. New promising innovations in breast MRI include fast abbreviated MRI, and functional techniques including diffusion-weighted imaging and magnetic resonance spectroscopy are promising particularly as regards to treatment response.
