1. To review the normal anatomy and MR appearance of the normal ovary.2. To be familiar with the cases in which the detection of ipsilateral or contralateral normal ovary offers clue or pitfall in diagnosing gynecologic neoplasm.

Accurate detection of pelvic masses and differentiation between uterine and ovarian masses are very important for planning a treatment strategy of gynecologic mass. In most cases, detection of an ipsilateral normal ovary is an important clue in excluding the possibility of ovarian tumors and detection of normal ovary in one side of pelvic cavity is a clue in diagnosing the opposite-side ovarian tumor or uterine tumor. However, in a small percentage of ovarian tumors, the detection of eccentric ovarian tissue surrounding the mass can confirm the ipsilateral ovarian origin of the mass. Rarely, the normal-appearing ipsilateral ovary can be seen in ovarian sex cord-stromal tumors originating from the periphery of the ovary. The purpose of this exhibit is to review the normal anatomy and MR appearance of the ovary and to illustrate the interesting cases in which the detection of ipsilateral or contralateral normal ovary offers clue or pitfall in diagnosing gynecologic neoplasm.
