Outcomes in Sonographically Categorized Complex Cystic Breast Lesions

Area of Science:

• Radiology
• Oncology
• Breast Imaging

Background:

• Complex cystic breast lesions require careful evaluation to distinguish benign from malignant conditions.
• Sonographic features play a crucial role in assessing breast lesion characteristics.

Purpose of the Study:

• To determine malignancy rates for different sonographic categories of complex cystic breast lesions.
• To investigate the outcomes and sonographic features associated with complex cystic breast lesions.

Main Methods:

• Retrospective analysis of 124 women with complex cystic breast lesions.
• Classification of cysts into four sonographic categories based on septa/wall, intramural nodule, and solid/cystic ratio.
• Evaluation of sonographic features including size, margin, axis ratio, and vascularity against histopathological and follow-up results.

Main Results:

• An overall malignancy rate of 8.8% was observed (11 malignant, 113 benign).
• Category 3 (solid/cystic ratio < 1) contained the majority of malignant tumors (82%).
• Vascularity, irregular margins, and a short-to-long axis ratio ≥ 1 were highly accurate indicators of malignancy.

Conclusions:

• Tissue sampling is recommended for all complex cysts due to the risk of malignancy and overlapping sonographic features.
• Sonographic evaluation should consider both internal morphology and other features like vascularity and margins.
• Accurate characterization of complex cystic breast lesions is essential for appropriate patient management.
