Spontaneously Infarcted Fibroadenoma Mimicking Breast Cancer

Spontaneous infarction is a rare complication occurring in fibroadenomas of the breast, 1 so it is not usually considered in differential diagnoses because of its rareness in the breast. There have been a few cases in the literature that reported patients with infarcted fibroadenomas, but we found only 1 old report to date describing the sonographic features of an infarcted fibroadenoma. 2 Recently, the only case of an atypical infarcted fibroadenoma in an adolescent girl was reported, and it was a predominantly cystic mass. 3 However, our patient had a predominantly solid mixed echoic mass, and this case showed more detailed characteristics of a fibroadenoma with spontaneous infarction. We report this recent case of an infarcted fibroadenoma with high-resolution sonographic features.
