摘要

乳房腺狀囊狀癌是一種罕見之乳房腫瘤，目前只有少數文獻報告討論其影像表現。我們報告一位52歲女性病人，以可觸摸到之左側乳頭下腫塊為臨床表徵。超音波表現為一個邊緣清楚，分葉狀，低迴音之腫塊。乳房攝影呈現一個含有脂肪成分、放射透光狀腫塊，其型態表現有可能為缺陷瘤。由於腫塊變大，故病患接受手術，開刀結果為一源於脂肪瘤內之乳房腺狀囊狀癌。此－特殊影像表現形式尚未於文獻報告提出過。

並列摘要

Adenoid cystic carcinoma of the breast is a rare neoplasm and only a few articles have described the imaging findings of the disease. We report a 52-year-old woman who presented with a palpable mass beneath the left nipple. Ultrasound revealed a well-defined, lobulated, hypoechoic mass. Mammography demonstrated a radiopaque mass in a well-defined fat-containing lesion, suggestive of hamartoma. The patient underwent surgery due to enlargement of the tumor. The final diagnosis disclosed adenoid cystic carcinoma arising in a lipoma. The unique imaging findings have never been reported in literature.
