Implication

Imaging study demonstrates variable MR signal intensity and enhancement patterns in breast fibroadenomas, indicating that internal septation and lobulation provide more reliable diagnostic criteria.

Key Points

Identify the histopathologic features responsible for the diverse magnetic resonance imaging appearances of breast fibroadenomas.
Evaluated 23 fibroadenomas in 21 female patients aged 23–66 years using gadolinium-enhanced MR imaging.
Graded T2-weighted signal intensity, contrast enhancement kinetics, lesion shape, and internal septations, correlating each with microscopic histopathology.
Fibroadenomas exhibited three imaging profiles: high T2 signal with enhancement (n=11), low T2 signal with enhancement (n=3), and low T2 signal without enhancement (n=9).
Low T2 signal intensity and lack of enhancement correlated significantly with older patient age and dense sclerotic stroma.
A lobular, oval, or round morphology was observed in 83% of lesions (19 of 23), and internal septations occurred in 64% of enhancing masses (9 of 14), corresponding histologically to collagenous bands.
