An adnexal mass is defined as indeterminate on US when it cannot be confidently placed into either the benign or malignant category, even after thorough interrogation including Doppler assessment, or for which the site of origin, from the ovary, uterus or another pelvic structure, remains to be established [6]. 1, pp. By Steven Vasilev, MD CT Transvaginal ultrasonography reveals homogeneously diffuse low echoes in the cystic mass, which is known as ground-glass appearance. The ovaries, fallopian tubes, uterus, cervix and vagina (vaginal canal) make up the female reproductive system. The purpose of this paper is to illustrate MRI findings in neoplastic and nonneoplastic ovarian masses, separated into three groups: cystic, solid, and solid/cystic lesions. 13) [35,36]. Accessed May 5, 2021. Dermoid cyst with small amount of fat. Discrimination between benign and malignant adnexal masses by specialist ultrasound examination versus serum CA-125. Presence of thick wall or septa may suggest borderline lesions while the presence of solid components suggests carcinoma (Figure 5(c)). Areas of edema, occasionally with cyst formation, are also relatively common. 3, pp. R. N. Low and J. S.

Its solid components are likely to correspond to the microfollicular or fibrous area of the tumor [40]. They are mostly frequently bilateral. In: Abeloff's Clinical Oncology. https://trp.cancer.gov/spores/ovarian.htm. The use of intravenous contrast material may be helpful in assessing the malignant solid components (Figure 4). The pattern recognition approach described in this study can be acquired without particular difficulty by anyone who performs gynecological US examinations on a regular basis. Transvaginal ultrasonography shows a multilocular cystic mass and internal solid components with various echoes (arrows). Relatively low intensity on T2-weighted images representative of fibrosis may be an important tool in the accurate diagnosis of this condition [33, 34] (Figure 3). There is no specific imaging feature for the diagnosis of tumorous unilocular cyst. Endometrioma occurs in the ovary where ectopic endometrial tissue is implanted. Doppler US demonstrated no blood flow in the lesion, which proved to be a localized blood clot after surgical resection (not shown). .

MRI criteria for the correct diagnosis and characteristics for differentiating benign from malignant conditions are shown in this paper. On MRI, an ill-defined lesion border resulting from trans fascial inflammatory spread may simulate a malignancy involving the ovary. Testa AC, Ferrandina G, Timmerman D, Savelli L, Ludovisi M, Van Holsbeke C, et al. In some cases, atypical features such as fluidfluid level, anechoic cyst, and multiple floating globules can be detected [23-25]. No potential conflict of interest relevant to this article was reported. 1, pp. They can invade nearby tissues and break off from an initial tumor to spread (metastasize) to other parts of the body. Hydrosalpinx is most often seen on US images as a hypoechoic adnexal mass, with a thick vascularized wall ring, associated with free fluid in the cul-de-sac. Being diagnosed with a suspicious massor with ovarian cancer itselfcan be scary and stressful. Mayo Clinic does not endorse companies or products. MRI is able to differentiate endometrioma from endometrioid adenocarcinoma and clear-cell adenocarcinoma that can develop within endometrial cysts, with an incidence of 0.61.0% [24]. In contrast, lesions that had a solid component with blood flow had a malignancy frequency of 32% in the overall study group and 50% in study participants who were more than 60 years old. If it has no features of either or a mixture of benign and malignant features, the test is considered inconclusive. Despite modern treatments, the risk of dying from ovarian cancer is still very real. Most mucinous cystadenocarcinoma, endometrioid adenocarcinoma, mucinous borderline malignancies, cystadenofibroma, struma ovarii, and granulosa cell tumor are categorized as multilocular solid cyst. Careers, Unable to load your collection due to an error. Weight loss. 20, no. Several types of tissue and fluid characterizing an ovarian mass can be distinguished at MRI on the basis of their signal intensity [17]. 3D fat saturated T1-weighted Spoiled Gradient Echo image (d) demonstrates the poor enhancement of mural protrusion corresponding to Rokitansky nodule (arrow). 163, no. .

Valentini et al. 7378, 1991. T1-weighted spin-echo images in the axial plane and T2-weighted fast spin-echo images obtained in the axial, sagittal, and coronal planes are usually employed to evaluate uterus, adjacent organs, pelvic floor, and broad ligaments, providing panoramic morphological view of the pelvis. Some adnexal tumors are fluid-filled, while others are solid. Metastasis to the ovary accounts for 5%-20% of ovarian tumors. However, malignant lesions can rarely present in the form of hyperechoic images [ 2 ]. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. On the other hand, edema and cystic formations are relatively common pathologic findings in the tumor because of necrosis. It is more often associated with an ovarian cyst or mass (approximately in 50% of cases) [27]. Carmina E, Oberfield SE, Lobo RA. What's known is that something occurs to create changes (mutations) in the DNA of cells in the endometrium the lining of the uterus. Within the left mass there is a posterior small papillary mural projection (b, white arrow). The RMI is determined by three main factors: Your healthcare provider then calculates the result: For example, if you had 2 ultrasound characteristics, you're post-menopausal, and your CA-125 level is 35, the formula would look like this: An RMI above 200 is considered suspicious. Overview Female reproductive system Enlarge image Adnexal tumors are growths of cells that form on the organs and connective tissues around the uterus. 5. 4) [17]. CA 125 test: A screening test for ovarian cancer? Ovarian hyperstimulation syndrome is an iatrogenic complication following ovulation stimulation in patients treated for infertility. National Institute for Health and Care Excellence (United Kingdom). Non-classic lesions include lesions with a solid component and blood flow detected on Doppler ultrasound. 16, no. Mucinous cystadenoma usually appears as multilocular cysts containing different echogenic materials, ranging from anechoic to diffuse low echogenic with floating echogenic foci that suggest a variety of mucin components (Fig. On MRI, these tumors typically manifest as a complex cystic mass associated with solid components of distinct low intensity on T2-weighted images [5, 7, 19].

Of these, pattern recognition approach has been shown to have the advantage of combing easy interpretation with a higher accuracy than other methods for predicting malignancy [4,6,7]. Ovarian teratomas: tumor types and imaging characteristics. privacy practices. The tumor belongs to the same histopathologic spectrum as an ovarian thecoma/ovarian fibrothecoma. Several proven methods are used to do this, including a subjective assessment, an ultrasound-based test called Simple Rules, or similar methods such as LR2 or RMI. Mayo Clinic. K. Kinkel, K. A. Frei, C. Balleyguier, and C. Chapron, Diagnosis of endometriosis with imaging: a review, European Radiology, vol. 283294, 2002. A small percentage of ovarian cancers are caused by genes changes you inherit from your parents. However MRI may be limited for detection of calcifications. These are also called echoes. Many healthcare providers use the Risk of Malignancy Index (RMI) either alone or combined with subjective assessment and ultrasound findings to predict the risk of malignancy in a mass on an ovary. This type reflects one of the typical features of ovarian malignancies. In these cases, the combination of calcifications demonstrated by ultrasonography or computed tomography and low intensity on T2-weighted MRI strongly suggests the diagnosis of Brenner tumor [35]. The cystic loculi are small, multiple, separated by thin septa and characterized by homogeneous low signal intensity on T1 and high intensity on T2-weighted images. Guerriero S, Mallarini G, Ajossa S, Risalvato A, Satta R, Mais V, et al. It also depends on your symptoms. A septum is defined as a thin strand of tissue running across the cyst cavity from one internal surface to the contralateral side [9]. 1, pp. 6th ed.

In patients with long-term use of intrauterine devices, actinomycetes are a frequent cause of chronic inflammation. When hemorrhagic necrosis occurs, the lesion may exhibit high intensity on T1-weighted images [29, 30] (Figure 2). The cells multiply quickly and can invade and destroy healthy body tissue. In particular, solid papillary projections are defined as any solid projections into the cyst cavity from the cyst wall with a length greater than or equal to 3 mm [9].

Ovarian dysgerminoma: a challenging clinical and sonographic diagnosis. The image is sometimes called a sonogram. Finally, the ancillary criteria of involvement of pelvic organs or the sidewall, ascites, and lymphadenopathy should be carefully evaluated to distinguish benign from malignant disease [5]. The presence of entrapped follicle between the fibrous tissue may be an important differentiating feature of this condition from ovarian fibromas [7]. If additional research supports the study findings, then the system could end up being a useful tool for radiologists that would spare many women the costs, stress and complications of surgery.

The characteristic US features of fibroma and fibrothecoma include the presence of a round, oval, or lobulated hypoechoic mass with minimal to moderate vascularity (Fig. A unilocular cystic mass with internal papillary projection is seen on transvaginal ultrasonography (arrows). Symptoms of ovarian cancer may include: It's difficult to say for sure whether an ovarian mass is cancerous without doing surgery. Ultrasound uses. The appearance of ovarian lesions on ultrasound is an effective predictor of cancer risk that can help women avoid unnecessary surgery, according to . J. This is a very non-specific finding that means that you have a mass which needs to be further looked at by . Note: normal left ovary with small normal follicle (c, void arrow). Retained products of conception (RPOC): . Studies show a specialist gives you the best chance of a successful surgery and a good survival rate, especially if they work in a cancer center that performs a lot of these surgeries. The typical US appearance is a complex cystic ovarian mass with homogenous low-level internal echoes and thick wall which is usually hypovascular at color Doppler evaluation. 18) [44,45]. 14).

Ovarian hyperstimulation syndrome: a current survey. While these findings on diagnostic ultrasound exams offer valuable triaging information, ultrasound has not been proven beneficial specifically as a screening exam for ovarian cancer. Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Coronal T2-weighted image (a) shows an enlarged right ovary with numerous small peripheral cysts representing displaced follicles (arrow). Color Doppler US helps the diagnosis identifying vascularized components within the mass. Heterogeneous and early enhancement pattern can be suggestive of malignancy. In order to differentiate benign and malignant ovarian masses, it is necessary to categorize ovarian masses into unilocular cyst, unilocular solid cyst, multilocular cyst, multilocular solid cyst, and solid tumor, and then to detect typical US features that demonstrate malignancy based on pattern recognition approach.
