Beyond the lung: recognizing incidental breast lesions on chest computed tomography

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Chest computed tomography (CT) is increasingly used, leading to more incidental breast findings.
• While often benign, these findings can sometimes indicate early breast cancer.
• Systematic breast assessment during chest CT interpretation is crucial.

Purpose of the Study:

• To provide an image-based overview of breast lesions on chest CT.
• To aid thoracic radiologists and clinicians in recognizing relevant breast findings.
• To improve the detection of breast abnormalities on non-dedicated chest imaging.

Main Methods:

• Review of normal breast anatomy and variants on chest CT.
• Description of CT features for benign and malignant breast lesions.
• Analysis of post-treatment changes and overlapping imaging features.

Main Results:

• Chest CT can visualize normal breast tissue, benign lesions, and suspicious findings.
• Key features like calcifications, enhancement patterns, and lymph node changes are discussed.
• Common pitfalls and diagnostic challenges are highlighted.

Conclusions:

• Familiarity with breast findings on chest CT promotes consistent interpretation.
• Improved awareness can reduce missed diagnoses and support timely management.
• Suspicious or indeterminate findings require further investigation.
