| Abstract |
|
Malignant mixed mllerian tumors (MMMTs) are unusual neoplasms occurring mostly in the endometrium. In the ovary, they are very rare and represent less than 1% of all ovarian malignancies. They are highly aggressive neoplasms comprising histologically of both epithelial and mesenchymal components. The cell type cannot be determined on the basis of appearance at magnetic resonance (MR) imaging, computed tomography (CT), or ultrasonography (US) but we diagnosed this case as endometrioid adenocarcinoma by MR imaging. Although the pathologic evaluation revealed the ovarian MMMT, mesenchymal components was very minute in the background of endometrioid adenocarcinoma components. The patient received the screening tests of ovarian carcinoma including transvaginal ultrasonography only 3months ago and she got negative results. During the exploration, a 15-cm sized mass looked like it has rapidly grown and ruptured spontaneously preoperatively. Herein we report a case of ovarian MMMT, which was diagnosed preoperatively as endometrioid adenocarcinoma by MR imaging with review of literatures. |
