Imaging Challenges in Diagnosing Triple-Negative Breast Cancer

Area of Science:

• Radiology
• Oncology
• Breast Imaging

Background:

• Triple-negative breast cancer (TNBC) is an aggressive subtype with a propensity for early metastasis.
• TNBCs pose diagnostic challenges due to their common presentation as circumscribed masses, lacking typical malignant features.

Purpose of the Study:

• To review the multimodality imaging appearances of TNBC.
• To guide radiologists in distinguishing TNBC from benign entities.
• To highlight subtle features aiding in timely and accurate TNBC diagnosis.

Main Methods:

• Review of multimodality imaging (mammography, US, MRI) of TNBC.
• Analysis of imaging characteristics that mimic benign conditions.
• Emphasis on US image optimization for improved detection.

Main Results:

• TNBCs often present as discrete masses with circumscribed margins and hypoechoic to anechoic echogenicity.
• These features can lead to misinterpretation as benign fibroadenomas or cysts.
• Subtle imaging findings can indicate malignancy and aid diagnosis.

Conclusions:

• Radiologists must be aware of TNBC's potential to mimic benign lesions.
• Careful mammographic and sonographic evaluation is crucial for accurate diagnosis.
• Recognizing specific imaging characteristics improves diagnostic accuracy and patient outcomes.
