Giant breast masses: A pictorial essay

Area of Science:

• Radiology
• Pathology
• Oncology

Background:

• Giant breast lesions present diagnostic challenges.
• Imaging modalities like mammography and ultrasound are crucial for characterization.
• Pathological examination is essential for definitive diagnosis.

Purpose of the Study:

• To illustrate the imaging and pathological features of diverse giant breast lesions.
• To highlight the utility of mammography and ultrasound in evaluating these lesions.
• To discuss the diagnostic accuracy limitations of needle biopsy for large or heterogeneous masses.

Main Methods:

• Pictorial essay format showcasing imaging findings.
• Correlation of imaging features with pathological diagnoses.
• Review of diagnostic workup including mammography, ultrasound, and biopsy.

Main Results:

• Certain lesions like lipomas and hamartomas have characteristic mammographic appearances.
• Ultrasound aids in differentiating lesions by identifying features such as posterior enhancement, cystic/solid components, internal septations, or increased vascularity.
• Mammography alone may be insufficient for distinguishing benign from malignant giant breast lesions.

Conclusions:

• A combination of imaging techniques, including ultrasound, is vital for characterizing giant breast lesions.
• For large or heterogeneous lesions, surgical excision may be necessary to overcome sampling errors and ensure accurate pathological diagnosis.
• Accurate diagnosis of giant breast lesions is critical for appropriate patient management.
