Imaging features of bilateral breast abnormalities.

Area of Science:

• Radiology
• Oncology
• Pathology

Background:

• Bilateral breast abnormalities present diverse causes, biologic profiles, and imaging characteristics.
• Advancements in imaging, particularly magnetic resonance imaging (MRI), enhance detection of subtle contralateral breast abnormalities in patients with unilateral disease, especially breast cancer.
• Some diseases inherently affect both breasts concurrently.

Purpose of the Study:

• To systematically review and describe the imaging features of bilateral breast abnormalities.
• To cover both common diseases and those that simultaneously involve both breasts.
• To enhance diagnostic accuracy and guide appropriate treatment by detailing imaging and clinical presentations.

Main Methods:

• Literature review of studies focusing on bilateral breast abnormalities.
• Analysis of imaging findings across various modalities, with emphasis on MRI.
• Correlation of imaging features with clinical presentations and histopathological data.

Main Results:

• Detailed descriptions of characteristic imaging findings for a spectrum of bilateral breast diseases.
• Identification of imaging patterns differentiating common unilateral diseases presenting bilaterally from true simultaneous bilateral processes.
• Highlighting the role of advanced imaging in detecting subtle contralateral findings.

Conclusions:

• A comprehensive understanding of bilateral breast abnormality imaging is essential for clinicians.
• Accurate interpretation of imaging features aids in preventing misdiagnosis and ensures timely, adequate patient treatment.
• This review serves as a resource for radiologists and oncologists managing patients with bilateral breast abnormalities.
