Cystic Breast Lesions: Diagnostic Approach and US Assessment

Area of Science:

• Radiology
• Medical Imaging
• Oncology

Background:

• Cystic breast lesions are common findings in breast imaging.
• Accurate classification is crucial for patient management and reducing unnecessary procedures.

Purpose of the Study:

• To review the sonographic classification of cystic breast lesions.
• To correlate findings with Breast Imaging Reporting and Data System (BI-RADS) categories.

Main Methods:

• Review of sonographic criteria for differentiating cystic breast lesions.
• Application of BI-RADS classification system.

Main Results:

• Simple cysts are BI-RADS category 2 (benign).
• Complicated cysts are BI-RADS category 3 (probably benign).
• Clustered microcysts are BI-RADS category 2 (benign).
• Complex cystic and solid masses are BI-RADS category 4 (suspicious), often requiring biopsy.

Conclusions:

• Meticulous ultrasound technique is essential for accurate cystic breast lesion assessment.
• Appropriate classification reduces unnecessary follow-up and biopsies.
• Correct diagnosis prevents missed or dismissed cancers.
