Fetal Ovarian Cysts: Prenatal Diagnosis Using Ultrasound and MRI, Management and Postnatal Outcome—Our Centers Experience

The present study provides our clinical experience regarding the imaging diagnosis, management and postnatal outcome of neonates prenatally suspected of having developed ovarian cysts. This multicenter observational study included patients diagnosed prenatally with fetal ovarian cysts and follow-up in the postnatal period. Descriptive statistics were used to render the information regarding the prenatal imaging aspect of the fetal pelvic masses using ultrasound and/or MRI, prenatal surveillance and postnatal neonate’s immediate outcome, indications leading to surgery and pathologic aspect. The inclusion criteria were fulfilled by 21 patients. The mean gestational age at the time of initial diagnosis was 31.28 weeks of gestation (WG). Only five out of 21 cysts regressed completely during pregnancy without postnatal complications. In addition, 11 out of 21 infant’s required surgical treatment in the first two weeks after birth, mainly for ovarian torsion. Five out of 21 neonates were referred to postnatal follow-up clinically and by ultrasound, but three out of five cases required emergency surgical treatment for acute complications. Ultrasound plays a major role in the diagnostic of fetal ovarian cyst. From our experience, MRI does not bring supplementary data or change the management. Spontaneous resolution of fetal ovarian cysts is to be expected but the ovarian mass could lead to serious complications, if resolution does not occur in due time.

Primary female genital system lymphoma complicated by a recurrent mucinous borderline ovarian tumor: a case report and review of the literature

Background Primary female genital system lymphoma (PFGSL) is an infrequent entity. All genital organs may be affected, and most PFGSLs are localized to the cervix, uterine body, and ovaries. The clinical manifestations are nonspecific, which complicates a timely diagnosis. We report an unexpected case of PFGSL and discuss the disease characteristics by reviewing the literature. Case presentation A 48-year-old G3/P2 woman presented to the Department of Gynecology with a physical examination. Ultrasound examination and CT revealed pelvic masses. The woman underwent surgical treatment because of the pelvic masses and underwent a hysterectomy for a recurrent mucinous borderline ovarian tumor. However, the results of the postoperative pathological examination showed diffuse large B-cell lymphoma of the endometrium. After four courses of chemotherapy, the woman was in good condition. The clinical manifestations were nonspecific, which made a timely diagnosis complex. Conclusion This case highlights the importance of the difficulty in detecting early PFGSL early and how easily nonspecific manifestations can be ignored. It may lead to missing the best time for early treatment.

The Role of Ultrasound Guided Sampling Procedures in the Diagnosis of Pelvic Masses: A Narrative Review of the Literature

Ultrasound-guided sampling methods are usually minimally invasive techniques applied to obtain cytological specimens or tissue samples, mainly used for the diagnosis of different types of tumors. The main benefits of ultrasound guidance is its availability. It offers high flexibility in the choice of sampling approach (transabdominal, transvaginal, and transrectal) and short duration of procedure. Ultrasound guided sampling of pelvic masses represents the diagnostic method of choice in selected patients. We carried out a narrative review of literatures regarding the ultrasound-guided methods of cytological and histological evaluation of pelvic masses as well as the positive and negative predictors for the achievement of an adequate sample.

Metastatic gallbladder cancer to the ovary presenting as primary ovarian cancer: a case report

Background Krukenberg tumors are uncommon and are indicative of an ovarian metastatic carcinoma that originates from another site of primary malignancy. The majority of metastases to ovaries are derived from the stomach and colon. We present a rare case of a metastatic ovarian malignant tumor that originated from gallbladder adenocarcinoma. Case presentation A 45-year-old premenopausal Korean woman presented with abdominal distension. Bilateral multiseptated ovarian tumors and a wall-thickened gallbladder were found on abdominal computed tomography. The patient was diagnosed with metastatic ovarian carcinoma arising from gallbladder adenocarcinoma and was treated with adjuvant chemotherapy. Conclusions Metastases to the ovaries from other sites, including the gallbladder, are rare and usually resemble primary ovarian tumors. Therefore, potential metastatic ovarian tumors of newly diagnosed pelvic masses should be considered in differential diagnoses.

Approach to Gynecological Adnexal Masses

Gynecological pelvic masses are a common occurrence in women of all ages. The differential diagnosis is extensive and includes masses of all anatomical components of the female reproductive tract. This simple and refined approach leads the reader through the process of narrowing said differential. A thorough history and physical examination are essential steps that can hint to the appropriate investigations such as reproductive hormone levels, serum cancer biomarkers and imaging. Emphasis is put on ultrasound findings, helping differentiate not only diagnoses, but also the benign or malignant character of the mass. It also highlights the Risk of Malignancy Index I, commonly used in clinical practice to assess the risk of malignancy of a mass. Beyond the initial approach, some diagnoses and their management are discussed, from the very common functional cyst to the worrisome ovarian neoplasm, and mentioning more peculiar findings like tubo-ovarian abscess and leiomyoma.

Struma ovarii and peritoneal strumosis during pregnancy

Background Struma ovarii is a special type of ovarian dermoid cyst and accounts for approximately 2–3 % of all dermoid tumours. Benign struma ovarii may manifest as distant metastasis, called peritoneal strumosis, which makes it biologically similar to malignancy, and has been reported in limited cases but never discovered during pregnancy. Case presentation We report a patient with a history of right struma ovarii cystectomy. During pregnancy, pelvic masses with non-specific clinical presentation were found again. During the caesarean section, contralateral struma ovarii with dissemination of nodules in the peritoneal cavity was found, and pathology revealed that the masses were thyroid follicle ovarian goitres. Discussion and conclusions Recurrent benign struma ovarii with extraovarian dissemination is a rare aggressive clinical manifestation different from malignancy. It is emphasized that adequate assessment and complete resection of suspicious masses are of great importance.
