postmenopausal uterine leiomyoma with Hemorrhagic Cystic Degeneration Mimicking Ovarian Malignancy

摘要

Fibroid is the most common neoplasm of the uterus in the female pelvis during reproductive age. It is usually the major problem and the reason for visiting a gynecologist. It is nearly impossible to determine their true incidence accurately, although the frequently quoted incidence of 50% found at postmortem examinations seems reasonable [1 ]. Uterine fibroid is a benign tumor composed mainly of smooth muscle cells but containing varying amount of fibrous connective tissue. The diagnosis is often easily confirmed noninvasively by ultrasonography, and the accuracy and sensitivity is high especially when the uterus is less than 10 weeks' size. However, localization of fibroids in a larger uterus or when there are many tumors is limited [2]. The characteristics of fibroids are commonly well-defined, concentric, solid, and hypoechoic.
