Mature cystic teratomas are benign germ cell tumors and, depending on the size, may be at risk for torsion. These ovarian masses can cause the ovarian vasculature to twist upon itself and inhibit blood flow, resulting in partial to complete torsion. If detection and treatment are not prompt, a salpingo-oophorectomy may be needed impeding future fertility. This case describes a young woman with acute left adnexal pain where sonography aided in the diagnosis of ovarian torsion caused by a large mature cystic teratoma. Transabdominal sonography was used, aided by extended field-of-view technology for characterization of the mass. The sonographic attributes of mature cystic teratomas vary, but careful evaluations can lead to an accurate diagnosis to aid in surgical procedures. The patient underwent an exploratory laparotomy, which resulted in a left ovary oophorectomy and excision of the mass.

“…Such topographicanatomical peculiarities can be considered standard for the fetuses of the given age group. Though they can be indicative of developmental retardation at the late stages of the perinatal development, which is not mentioned in the works of certain researchers [9,14,16,19,23,25].…”

Defects of the urinary system take the 3rd place by their occurrence including 6% of developmental defects of the female reproductive organs. Therefore modern studies in the field of perinatal anatomy are of a special importance. Objective of the study was to determine age peculiarities in the structure and topography of the fetal ovaries as well as similar and different tendencies in changes of the ovarian morphological parameters of the two groups of fetuses, remote in time. The study was conducted in the two groups of human fetuses, 4-10 months of development, 161.0-500.0 mm of the parietal-calcaneal length. The first group consisting of 35 specimens divided into 7 subgroups according to the month of development (4, 5, 6, 7, 8, 9 and 10), was formed with fetuses died during 2017-2019 years. The second group included specimens of fetuses collected during 1970-1990. The obtained results were statistically processed in the licensed statistical package “Statistica 6.0”. The character of distribution for every obtained variation lines, mean values for every sign, standard quadratic deviation, percentile scope of the parameters were evaluated. Reliability of differences in the indices between independent quantitative values was determined by means of Mann-Whitney U-criterion. The conducted study determined that the ascending position of the ovaries in the early fetuses can be considered normal for the given age group, though the topography is indicative of developmental retardation at the late stages of perinatal development. The length of the ovary in both groups increases gradually from the 4th to the 10th month with a certain delay during the 6th month. It might be associated with intensified growth of its parenchyma, and intensive increase of its width and length respectively. The majority of the ovarian parameters of 9-10 month fetuses do not differ reliably, which is indicative of a complete development of the ovarian definite structure at the 9th month of the intrauterine development. Comparison of the parameters of the two groups of fetal specimens, remote in time, is indicative of the fact that in the majority of the parameters they do not differ. Although in modern studies the length of the right ovary in 8-month fetuses, and the length of the left ovary in 7-month fetuses is shorter than that of the archival specimens. Similarly the width of the left ovary in 4-month fetuses appears to be reliably shorter than that of the archival specimens. The thickness of the right ovary of 7 and 10-month modern fetuses is reliably less than that of the appropriate groups of the archival specimens. The thickness of the left ovary of modern fetuses is reliably less than that of the archival specimens during the 10th month. Therefore, a reliable difference was found only in 2 pairs of the parameters included in 42 pairs of the examined morphometric parameters of both groups. It is indicative of inconsiderable changes of these parameters during the period of 27-49 years.

Objective To describe the clinical and ultrasound features of ovarian mature cystic teratomas (MCTs). Methods This was a retrospective study. From the International Ovarian Tumor Analysis (IOTA) database, we identified patients with a histologically confirmed diagnosis of MCT who had undergone transvaginal ultrasound examination between 1999 and 2016 (IOTA phases 1, 2, 3 and 5) in one of five centers. Ultrasound was performed by an experienced examiner who used the standardized IOTA examination technique and terminology. In addition to extracting data from the IOTA database, available two‐dimensional grayscale and color or power Doppler images were reviewed retrospectively to identify typical ultrasound features of MCT described previously and detect possible new features using pattern recognition. All images were reviewed by two independent examiners and further discussed with two ultrasound experts to reach consensus. Results Included in the study were 454 patients with histologically confirmed MCT. Median age was 33 (range, 8–90) years and 66 (14.5%) patients were postmenopausal. Most MCTs were described by the original ultrasound examiner as unilocular (262/454 (57.7%)) or multilocular (70/454 (15.4%)) cysts with mixed echogenicity of cystic fluid (368/454 (81.1%)), acoustic shadowing (328/454 (72.2%)) and no or little vascularization on color Doppler (color score 1, 240/454 (52.9%); color score 2, 123/454 (27.1%)). The median largest lesion diameter was 66 (range, 15–310) mm. A correct preoperative diagnosis of MCT was suggested by the original ultrasound examiner in 372/454 (81.9%) cases. On retrospective review of ultrasound images of 334 MCTs that had quality sufficient for assessment, ‘dots and/or lines’ and/or ‘echogenic white ball’ (typical features according to the literature) were present in 271/334 (81.1%) masses. We identified four new ultrasound features characteristic of MCT: ‘cotton wool tufts’, ‘mushroom cap sign’, ‘completely hyperechogenic lesion’ and ‘starry sky sign’. At least one classical or novel ultrasound feature was present in 315/334 (94.3%) MCTs. Twenty‐nine (8.7%) MCTs manifested vascularized solid tissue, of which seven exhibited no typical features. Conclusion We provide a comprehensive overview of conventional and newly described ultrasound features of MCTs. Only a small proportion of MCTs did not manifest any of the typical features. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.
