Adenomyomatous polyp mimicking hydatidiform mole on ultrasonography

The authors present a case report of a 62-year-old woman who experienced irregular genital bleeding. Although the serum hCG level was extremely low, transvaginal ultrasonography revealed vesicle pattern in the uterine cavity, suggesting trophoblastic disease. Hysterectomy was performed and histological diagnosis was adenomyomatous polyp. To our knowledge, this is the first report that the adnomyomatous polyp can demonstrate the vesicle pattern on ultrasonography.
