OBJECTIVE. The purpose of this study was to analyze and compare the
mammographic and sonographic appearances of benign and malignant mucocele-like
tumors.
CONCLUSION. The mammographic appearance of mucocele-like tumor of
the breast is characterized as pleomorphic calcifications, often increasing in
number. Microcalcifications in malignant mucocele-like tumors extended over a
wider area than those in benign mucocele-like tumors. Sonography often shows
cysts with calcified or noncalcified mural nodules.
