title: Sclerosing lobular hyperplasia: sonographic pathologic correlation.
abstract: The objective was to evaluate the sonographic findings of sclerosing lobular hyperplasia (SLH) of the breast and to correlate the sonographic findings and the pathologic features. This study consisted of 9 patients with pathologically proven sclerosing lobular hyperplasia who had undergone a preoperative imaging study. We retrospectively reviewed 9 ultrasonograms and 6 mammograms. In each patient mammographic findings including, shape and margin, and ultrasonographic findings including the size, length-to-anteroposterior ratio, shape, margin, internal echo pattern, and the presence and location of internal echogenic septum, were evaluated. Histopathologic correlations focused on characteristic imaging findings. Of the 6 mammograms, 4 cases showed a lobular (3 of 6) or an oval shaped mass (1 of 6) with a partly obscured margin (4 of 6). The remaining 2 cases showed heterogeneously dense breast without visible mass. Ultrasonograms showed a lobular (5 of 9) or an oval (4 of 9) shaped mass with a circumscribed margin (9 of 9). The mean length/anteroposterior ratio was 1.98. Intratumoral echogenic septum was present in 8 cases. Six cases had a peripherally arising septum. Histopathologic review revealed that this septum was correlated to interlobular sclerosis. A peripherally arising intratumoral echogenic septum on ultrasonography seen in SLH might be explained by the interlobular sclerosis.
