“…Mucinous cystadenocarcinomas were of homogenous appearance with uniformly sized and evenly distributed locules. In a previous study, the appearance of most mucinous cystadenocarcinomas was more benign than that of serous cystadenocarcinomas (14), and in our study this was also the case. Compared with mucinous cystadenocarcinomas, serous cystadenocarcinomas were irregular and lobulated, with locules of uneven size and homogenous attenuation.…”

Epithelial cancers are the most common type of ovarian malignancy, and may be serous (75 %), mucinous (20 %) or a mixture of other histologic types (5 %). In terms of their pathology, tumor behavior and prognosis, serous and mucinous ovarian cancers are different, and their clinical differentiation is not easy. In order to determine the basis on which these two diseases may be differentiated, we have therefore evaluated their respective imaging features. Materials and MethodsDuring a recent six-year period, CT images were obtained from 50 consecutive ovarian cystadenocarcinoma patients. Pathologic examination revealed 25 mucinous cystadenocarcinomas (one bilateral) in 24 patients aged 45 to 72 (mean, 59) years, and 47 serous cystadenocarcinomas (21 bilateral) in 26 patients aged 16 to 71 (mean, 43) years. In all patients, CT images were ob- Purpose : To assess the differences between imaging findings of mucinous and serous cystadenocarcinomas of the ova r y, as seen on computed tomography (CT). CT Differentiation of Ovarian Mucinous and Materials and Methods :The CT findings of 24 patients with mucinous cystadenocarcinoma (25 tumors) and 26 with serous cystadenocarcinoma (47 tumors) of the ova r y were retrospectively analysed. Images were evaluated for tumor size, contour, CT attenuation of locules within the mass, the presence of septal vegetation, the proportion of solid portion within the mass, the presence of calcification, and carcinomatosis peritonei.Results : Mucinous cystadenocarcinomas tend to have a smooth contour (96%), va r iable CT attenuation of locules (80 %), and even size of locules within the mass (88.0 %). Serous cystadenocarcinomas, on the other hand, tend to have an irregular lobulated contour (89.4 %), unevenly sized locules (76.6%), septal vegetation (57.4 %), and a prominent solid portion (59.6 %). Bilaterality and carcinomatosis peritonei were more common in serous than in mucinous cystadenocarcinoma. Conclusion : Features which are valuable for the differentiation of mucinous and serous cystadenocarcinomas of the ova r y, as seen on CT, are tumor size, contour, va r ying locule attenuation and size, septal vegetation, a solid portion, bilaterality and peritoneal seeding.

“…Most adnexal masses are suspected when patients presents with complaint of abdominal mass , or pain which later on is further evaluated by ultrasonography. Once we come across a neoplastic ovarian mass, it is imperative to decide whether the mass is benign or malignant to determine further treatment plan, and this is based largely on imaging appearances in addition to laboratory findings (Buy et al, 1991;Parkin et al, 2005) The most commonly employed imaging modality for pelvic pathologies and adnexal masses is ultrasonography. Although it is the standard method for the preliminary assessment, due to its low cost, easy availability and high sensitivity of approximately 85-100%, it is still lagging behind CT and MRI due to its variable specificity rate (50-100%).…”

“…Ultrasound has been found to be as good as or superior to CT for discrimination between different types of pelvic tumor [109,129]. MRI has also been used to characterize different types of adnexal tumor in the female pelvis [130][131][132][133][134][135][136].…”

This chapter summarizes the diagnostic performance (sensitivity, specificity, positive and negative likelihood ratios) of ultrasound, computer tomography, and magnetic resonance imaging in the diagnosis of various gynecological diseases and tumors. Positron emission tomography is not discussed. Imaging in infertility, in the diagnosis of Mullerian duct anomalies and in gynecological oncology (staging of gynecological cancers, diagnosis of recurrence of gynecological cancer, diagnosis of trophoblastic tumors) is not dealt with.Ultrasound is the first line imaging method for discrimination between viable intrauterine pregnancy, miscarriage and tubal pregnancy in women with bleeding and/or pain in early pregnancy, for discrimination between benign and malignant adnexal masses and for making a specific diagnosis in adnexal tumors (e.g., dermoid cyst, endometrioma, hemaorrhagic corpus luteum, ectetera), for diagnosing intracavitary uterine pathology in women with bleeding problems, and for confirming or refuting pelvic pathology in women with pelvic pain. Magnetic resonance imaging may have a role as a secondary test in the diagnosis of adenomyosis, 'deep endometriosis' (e.g., endometriosis in the rectovaginal septum or in the utero-sacral ligaments), and in the diagnosis of extremely rare types of ectopic pregnancy (e.g., in the spleen, liver or retroperitoneum).
