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