| PURPOSE : To correlate sonographic appearance and histopathologic findings of fibroadenomas.
MATERIALS and METHODS :Forty-one biopsy-proven fibroadenomas were retrospectively evaluated for sonographic-pathologic
correlation. The fibroadenomas were histologically classified into sclerotic, myxoid, glandular and
mixed type. The stromal cellularity and fibrosis were also classified into mild and severe. The internal echotex-ture
and posterior acoustic enhancement of mass in ultrasonogram were correlated with histopathologic find-ings .
RESULTS : The pathologic types of fibroadenomas were sclerotic in sixteen, myxoid in thirteen, and glandular or
mixed in each of six cases. Most of the sclerotic type showed hypoechoic internal echotexture(68.8%) and myx-oid
and glandular types showed isoechoic internal echotexture(84.6%, 83.3% respectively). The hypoechoic
masses showed 12 cases of mild(75.0%) and 4 cases of severe(25.0%) in cellularity and 3 cases of mild(18.7%)
and 13 cases(81.3%) of severe degree in fibrosis. Most of the myxoid type(77%) showed posterior enhance-ment,
and most of the sclerotic type(87.5%)did not show posterior enhancement on ultrasonogram. Posterior
enhancement was absent in 22 cases, in which 4 cases(18.2%) showed mild and 18 cases(81.2%) showed severe
degree of fibrosis .
CONCLUSION : Sclerotic type with mild cellularity and severe fibrosis on histopathology showed hypoechogenicity
on ultrasonogram; whereas myxoid and glandular types were predominantly isoechoic. Most of the myxoid
type showed posterior enhancement. Sclerotic type with mild cellularity and severe fibrosis did not show poste-rior
enhancement. |
