AI Article Synopsis
- There is limited literature on parenchymal breast cysts in men, prompting a study to enhance understanding and management of this rare condition.
- In a review of 5,425 male breast imaging cases from 1995 to 2020, only 19 (0.4%) were confirmed as breast cysts, with an average age of 41.6 years for patients.
- The most common reason for cyst detection was a palpable lump, and findings showed that the cysts were generally benign with no cases of malignancy or atypia found during follow-up.
Article Abstract
Objective: Parenchymal breast cysts are considered to be rare in men and are sparsely described in the literature. The purpose of this study was to review our institution's experience with male breast cysts in an effort to improve overall understanding and management of this rare entity.
Methods: An institutional review board-exempt retrospective study was performed. Radiology reports for males who underwent mammogram and/or breast ultrasound at any of our institution's primary or satellite locations from January 1995 to January 2020 were screened to find males with breast cysts. If cysts were reported and images were available, case review was performed to confirm parenchymal breast cyst(s) and patient characteristics were collated.
Results: Of 5425 male cases presenting for breast imaging, 19 (0.4%) cases of male breast cysts were confirmed, with a mean patient age of 41.6 years (range: 2-81 years). The most common indication leading to cyst discovery was a palpable lump, corresponding to the site of the cyst in 5 (26.3%) patients and near the site where cyst(s) were ultimately discovered in 7 (36.8%) patients. There were 8 (42.1%) instances of cysts without concurrent gynecomastia. Three (15.8%) men underwent needle sampling. There were no cases of atypia or malignancy on needle biopsy or on subsequent clinical follow-up, with median clinical follow-up of 70.3 months (range: 3.3-259.4 months).
Conclusion: Male breast parenchymal cysts are rare, but their prevalence is likely underestimated. If detected incidentally or upon targeted evaluation, biopsy may be averted if classic benign cyst features are identified.

Faster Acquisition and Improved Image Quality of T2-Weighted Dixon Breast MRI at 3T Using Deep Learning: A Prospective Study.
Korean J Radiol
January 2025
Department of Diagnostic and Interventional Radiology, University Medical Center Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.
Objective: The aim of this study was to compare image quality features and lesion characteristics between a faster deep learning (DL) reconstructed T2-weighted (T2-w) fast spin-echo (FSE) Dixon sequence with super-resolution (T2) and a conventional T2-w FSE Dixon sequence (T2) for breast magnetic resonance imaging (MRI).
Materials And Methods: This prospective study was conducted between November 2022 and April 2023 using a 3T scanner. Both T2 and T2 sequences were acquired for each patient.
Imaging Characteristics of Primary Mucinous Cystadenocarcinoma of the Breast: A Case Report and Literature Review.
Curr Med Imaging
January 2025
Department of Pathology, Affiliated Jinhua Hospital Zhejiang University School of Medicine, Jinhua, Zhejiang, 32100, P. R. China.
Introduction: Mucinous Cystadenocarcinoma (MCA) of the breast remains a relatively rare condition, and to date, there is no systematic summary of its imaging manifestations. Therefore, this report presents a detailed account of the diagnosis and treatment of mucinous cystadenocarcinoma in a 40-year-old woman, with a particular focus on imaging findings. Additionally, we conducted a comprehensive literature review on this disease and summarized its key imaging features.

Breast Imaging Department, Red Cross Hospital Munich, Munich, Germany.
Background: A significant proportion of false positive recalls of mammography-screened women is due to benign breast cysts and simple fibroadenomas. These lesions appear mammographically as smooth-shaped dense masses and require the recalling of women for a breast ultrasound to obtain complementary imaging information. They can be identified safely by ultrasound with no need for further assessment or treatment.

Background: Notch signaling, a conserved mechanism of cell-to-cell communication, plays a crucial role in regulating cellular processes such as proliferation and differentiation in a context-dependent manner. However, the specific contribution of Notch signaling to the progression of polycystic kidney disease (PKD) remains unclear.
Methods: We investigated the changes in Notch signaling activity (Notch1-4) in the kidneys of autosomal dominant PKD (ADPKD) patients and two ADPKD mouse models (early and late onset).
A rare case of hydatid cyst presenting as a breast cancer. A case report.

Article Synopsis
- Hydatid disease, caused by the Echinococcus parasite, is a serious health issue in endemic areas, and breast involvement is notably rare; this case involves a 34-year-old Ethiopian woman initially misdiagnosed with breast cancer.
- The patient presented with a painless swelling in her left breast that persisted for nine months, without symptoms typically associated with cancer, such as discharge or skin changes.
- Diagnostic imaging and tests ultimately confirmed that the mass was a hydatid cyst, highlighting the need for healthcare professionals to consider less common conditions in their diagnosis of breast masses in endemic regions.
