ESUR guidelines for MR imaging of the sonographically indeterminate adnexal mass: an algorithmic approach Abstract A significant proportion of adnexal masses detected by sonography are indeterminate. Either their organ of origin is uncertain or it is unclear whether their nature is benign or malignant. MR imaging of the sonographically indeterminate adnexal mass can resolve most of these uncertainties. Most indeterminate masses result from common benign conditions and women with such masses can avoid unnecessary or inappropriate surgery. For the minority of women whose masses are malignant, use of MR imaging rather than a 'wait and watch' strategy of repeat ultrasound (US) results in a more timely diagnosis. There are simple diagnostic steps in the MR imaging assessment which direct an algorithmic and problem-solving approach based on signal characteristics and morphology. MR imaging should provide a more timely diagnosis and, thereby, guide the management of the patient with reduced costs of investigation and treatment.

“…Thus, careful evaluation of the ipsilateral ovary may aid the differentiation between ovarian fibroma and uterine leiomyoma. The cystic degeneration of fibromas has been reported to lead to the pre-operative misdiagnosis of malignant ovarian epithelial and collision tumors in certain cases (5,6). Larger or twisted tumors may result in various MR imaging findings which reflect the degenerative changes, including cystic degeneration, edematous changes, hemorrhagic infarction or necrosis as a result of torsion and myxomatous changes (4,9).…”

Pelvic tumors with normal-appearing shapes of ovaries and uterus presenting as an emergency (Review)

et al. 2012

Abstract. Abdominal pain with an associated pelvic mass is a common problem in everyday practice. Concerns about ectopic pregnancy, torsion of an enlarged ovary or malignancy usually dominate the diagnostic evaluation. On physical and imaging examination, when a palpable painful mass is present in the pelvis and the two ovaries and uterus are detected in their normal anatomical locations, the content and origin of the lesions may be significant in narrowing the pre-operative differential diagnosis. Thus, the emergent pelvic indications discussed in this review should be considered. The causes of acute abdominal pain are few in number and therefore an accurate diagnosis may be most frequently made at the time of exploratory laparotomy. Contents1. Introduction 2. Ovarian fibroma 3. Fat-containing tumors in the pelvic cavity 4. Pedunculated myoma 5. Tumor within an accessory ovary 6. Pelvic hematoma 7. Other problems 8. Conclusion IntroductionAbdominopelvic pain with an associated pelvic mass is a common emergency. These patients create a management dilemma for most emergency physicians. This problem usually stems from the inability of the physical examination to reliably differentiate between a potential surgical problem (i.e., torsion of an enlarged ovary, pelvic abscess) and a non-surgical etiology (i.e., ovarian cyst, uterine myoma). Ultrasonograpy (US), magnetic resonance (MR) and/or computed tomography (CT) are the gold standard imaging modalities used to differentiate pelvic masses in female patients presenting with abdominopelvic pain as an emergency.Ovarian tumors and uterine myoma constitute the most common masses in the female pelvis (1,2). The torsion of enlarged ovaries is one of the most common surgical gynecological emergencies (1). The differential diagnosis includes twisted exophytic ovarian fibroma, pedunculated myoma, peritoneal lipoma and accessory ovary although it should be noted that these conditions rarely cause acute abdominopelvic pain. The purpose of this review was to summarize the differential diagnosis of pelvic masses associated with acute abdominal pain when normal-appearing ovaries and uterus are detected. Ovarian fibromaOvarian fibromas are the most commonly encountered subtype of sex cord-stromal tumors, accounting for 4-5% of all ovarian tumors (3-6). It is well known that MR imaging is useful in diagnosing ovarian fibromas, due to the characteristically low T1-and T2-weighted signal intensities of the tumors, caused by the presence of densely packed connective tissue (3-6). The main differential diagnosis of a solid adnexal mass with T2 hypointensity includes a uterine pedunculated myoma and an ovarian fibroma. In a retrospective analysis, crescentshaped ovarian tissue may be detected along the periphery of the tumor in approximately 50% of ovarian fibroma cases and a normal-appearing ovary closely attached to the tumor in certain lesions may be misdiagnosed as a subserosal leiomyoma (5-8).

O‐RADS MRI SCORE: An Essential First‐Step Tool for the Characterization of Adnexal Masses

The ovarian‐adnexal reporting and data system on magnetic resonance imaging (O‐RADS MRI) score is now a well‐established tool to characterize pelvic gynecological masses based on their likelihood of malignancy. The main added value of O‐RADS MRI over O‐RADS US is to correctly reclassify lesions that were considered suspicious on US as benign on MRI. The crucial issue when characterizing an adnexal mass is to determine the presence/absence of solid tissue and thus need to perform gadolinium injection. O‐RADS MR score was built on a multivariate analysis and must be applied as a step‐by‐step analysis: 1) Is the mass an adnexal mass? 2) Is there an associated peritoneal carcinomatosis? 3) Is there any significant amount of fatty content? 4) Is there any wall enhancement? 5) Is there any internal enhancement? 6) When an internal enhancement is detected, does the internal enhancement correspond to solid tissue or not? 7) Is the solid tissue malignant? With its high value to distinguish benign from malignant adnexal masses and its high reproducibility, the O‐RADS MRI score could be a valuable tool for timely referral of a patient to an expert center for the treatment of ovarian cancers. Finally, to make a precise diagnosis allowing optimal personalized treatment, the radiologist in gynecological imaging will combine the O‐RADS MRI score with many other clinical, biological, and other MR criteria to suggest a pathological hypothesis.Level of Evidence5Technical Efficacy Stage3.
