Abstract

PURPOSE
The purpose of this study was to determine if the sonographic features of mammary fibromatosis had correlation with the pathologic findings.
MATERIALS AND METHODS
We identified four cases of fibromatosis of the breast at our institution over a 10-year period. The patients were all women, and they ranged from 25 to 48 years of age (mean, 34.3 years). All four patients complained of palpable breast masses and were subsequently diagnosed with mammary fibromatosis. We retrospectively reviewed their imaging findings.
RESULTS
Mammography obtained in one patient revealed architectural distortion. On sonography, all four cases showed spiculated, irregular, hypoechoic masses that could not be differentiated from malignant lesions. After surgical excision and vacuum-assisted biopsy of the masses in four patients, there was no recurrence on clinical or sonographic follow-up over a 13-36 month period.
CONCLUSION
Although mammary fibromatosis is a very rare condition, it should be included in the differential diagnosis when an un-calcified, spiculated, irregular and hypoechoic masses are encountered on breast sonography.
