Liu X, Liu J, Chen L, Yang C, Hu Y, Liu Y. Giant ovarian solid and cystic masses mixed with three types of tumors: A rare case report and literature review. Heliyon 2024; 10:e35075. [PMID: 39161819 PMCID: PMC11332876 DOI: 10.1016/j.heliyon.2024.e35075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 07/16/2024] [Accepted: 07/22/2024] [Indexed: 08/21/2024] Open
Abstract
Background Most ovarian tumors exhibit a pure histological characteristic. Nevertheless, a combination of tumors with the same histogenetic origin but different histologic subtypes is relatively common. Additionally, co-occurrence of tumors with different histogenetic origins is very rare. Typically, these mixed tumors include mixed epithelial tumors, mixed epithelial-stromal tumors, mixed germ cell-sex cord-stromal tumors, and mixed germ cell tumors. However, mixed epithelial-sex cord stromal-lymphohematopoietic system tumors are rare. Currently, clinicians have limited knowledge of this type of tumor, and the epidemiology, diagnosis, and treatment of this disease are yet to be established. Case presentation We report a case of a 73-year-old woman with abdominal distension and pain for three months. Imaging evaluation revealed a large pelvic mass, with ultrasound suggesting a benign ovarian cyst along with leiomyoma. Furthermore, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a malignant tumor. Blood tests showed significant increases in CA125 and CA199 levels. The patient underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy. During the surgery, a large multinodular cystic solid mass was observed in the right ovary, and the maximum nodular diameter was 14.2 cm. The solid areas of the mass appeared gray-white and taupe, whereas the cystic areas contained clear liquid with smooth walls 0.2 cm thick and no intracystic solid areas. The left ovary had solitary nodules, the largest being 4 cm in diameter. Microscopic examination of the right ovary revealed three different cell types. The first type of cell area was analogous, round, fusiform, and staggered mixed cells with unclear boundaries and rare nucleolus or mitosis. The second type of cell area was the cystic dilatation area. The cyst wall was covered with a single layer of flat epithelium, rich eosinophilic cytoplasm, uniform nuclear chromatin, and no papillary structures. The third type was a diffuse lymphoid region with uniform medium-sized cells, rough nuclear chromatin and evident nucleoli and mitosis. The morphology of the left ovarian cell was single, which was consistent with the first type of cell area in the right ovary. Immunohistochemistry of the right ovary indicated that the first region expressed vimentin, inhibin-α, calretinin, SF-1, WT-1 and CD56, with Ki-67 at 5 %, and no CKpan expression. The second region expressed CKpan, with Ki-67 at 1 %. The third region expressed CD20, Pax-5, Bcl-6, Bcl-2, MUM1, CD45, and C-myc, with Ki-67 at 70 %, and positive IGH clonal gene rearrangement. Lastly, the pathological diagnosis was a mixed ovarian tumor in the right ovary, comprising thecoma-fibroma, serous cystadenoma, diffuse large B-cell lymphoma, and a thecoma-fibroma in the left ovary. A follow-up examination of the patient after 15 months showed no mass or lymph node enlargement in other parts of the body, and no recurrence or metastasis was observed. Conclusions We present a case of a postmenopausal woman with a rare combination of thecoma-fibroma, serous cystadenoma and diffuse large B-cell lymphoma in the ovary. To the best of our knowledge, this is the first reported case of such a combination. Typical pathological morphology and immunohistochemistry are crucial for the diagnosis of this disease. Owing to the limited knowledge of the disease, its pathogenesis and tissue origin are unknown. Clinicians should be careful about such patients. We believe this case report may provide some novel insights into the diagnosis and therapy of patients with this type of tumor.

Magnetic resonance imaging-based radiomics analysis of the differential diagnosis of ovarian clear cell carcinoma and endometrioid carcinoma: a retrospective study. Jpn J Radiol 2024; 42:731-743. [PMID: 38472624 PMCID: PMC11217043 DOI: 10.1007/s11604-024-01545-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 02/02/2024] [Indexed: 03/14/2024]
Abstract
PURPOSE To retrospectively evaluate the diagnostic potential of magnetic resonance imaging (MRI)-based features and radiomics analysis (RA)-based features for discriminating ovarian clear cell carcinoma (CCC) from endometrioid carcinoma (EC). MATERIALS AND METHODS Thirty-five patients with 40 ECs and 42 patients with 43 CCCs who underwent pretherapeutic MRI examinations between 2011 and 2022 were enrolled. MRI-based features of the two groups were compared. RA-based features were extracted from the whole tumor volume on T2-weighted images (T2WI), contrast-enhanced T1-weighted images (cT1WI), and apparent diffusion coefficient (ADC) maps. The least absolute shrinkage and selection operator (LASSO) regression with tenfold cross-validation method was performed to select features. Logistic regression analysis was conducted to construct the discriminating models. Receiver operating characteristic curve (ROC) analyses were performed to predict CCC. RESULTS Four features with the highest absolute value of the LASSO algorithm were selected for the MRI-based, RA-based, and combined models: the ADC value, absence of thickening of the uterine endometrium, absence of peritoneal dissemination, and growth pattern of the solid component for the MRI-based model; Gray-Level Run Length Matrix (GLRLM) Long Run Low Gray-Level Emphasis (LRLGLE) on T2WI, spherical disproportion and Gray-Level Size Zone Matrix (GLSZM), Large Zone High Gray-Level Emphasis (LZHGE) on cT1WI, and GLSZM Normalized Gray-Level Nonuniformity (NGLN) on ADC map for the RA-based model; and the ADC value, spherical disproportion and GLSZM_LZHGE on cT1WI, and GLSZM_NGLN on ADC map for the combined model. Area under the ROC curves of those models were 0.895, 0.910, and 0.956. The diagnostic performance of the combined model was significantly superior (p = 0.02) to that of the MRI-based model. No significant differences were observed between the combined and RA-based models. CONCLUSION Conventional MRI-based analysis can effectively distinguish CCC from EC. The combination of RA-based features with MRI-based features may assist in differentiating between the two diseases.

Abstract
Imaging plays a pivotal role in the diagnostic approach of women with suspected ovarian cancer. MRI is widely used for preoperative characterization and risk stratification of adnexal masses. While epithelial ovarian cancer (EOC) has typical findings on MRI; there are several benign and malignant pelvic conditions that may mimic its appearance on imaging. Knowledge of the origin and imaging characteristics of a pelvic mass will help radiologists diagnose ovarian cancer promptly and accurately. Finally, in special subgroups, including adolescents and gravid population, the prevalence of various ovarian tumors differs from that of the general population and there are conditions which uniquely manifest during these periods of life.

Abstract
PURPOSE To evaluate the combination of magnetic resonance imaging (MRI) findings and clinical features in diagnosing ovarian granulosa cell tumor (OGCT) and comparing OGCTs with other ovarian sex cord-gonadal stromal tumors (OSGTs). METHODS Women who underwent MRI and were surgically confirmed with OSGTs between January 2015 and January 2022 were included in the study. Histology was used as a primary method of diagnosis. T1WI, T2WI, and DWI MR scans were performed for all patients. All MR images were reviewed by two radiologists. The clinic baseline characteristics of all patients were recorded. RESULTS A total of 58 patients were enrolled, with 21 OGCTs found in 20 patients and 39 other OSGTs found in 38 patients. In terms of clinical, the proportion of vaginal discharge/bleeding and menstrual abnormalities were significantly higher in OGCTs than in the control group. A multivariate analysis of the combined clinical MRI revealed that symptomatic, T2 signals of the solid component, Honeycomb-sign, Swiss cheese-sign, and ADC values were independent features for discriminating between OGCTs and other OSGTs. Clinical features, MRI features, and a combined model were established; the areas under the curve of the three models in predicting OGCTs and other OSGTs were 0.694, 0.852, and 0.927, respectively. The DeLong test showed that the combined model had the highest efficiency in predicting OGCTs (p < 0.05), which was significantly different from the AUC of the other two models (p < 0.05). CONCLUSIONS Combining clinic and MRI findings helps differentiate OGCTs from other OSGTs. These results help optimize clinical management and indicate that radiologists should focus on clinical information to help improve diagnostic accuracy.

Abstract
About 5% of all ovarian tumors develop some form of hormonal activity. Only 1% of ovarian tumors will secrete androgens causing clinical hyperandrogenism. Most androgen-secreting neoplasms (ASN) derive from sex cord or stroma cells of the ovary and may affect both premenopausal and postmenopausal women. Typically, a patient will present reporting symptoms of rapidly increasing hyperandrogenization such as: hirsutism, acne, frontal/male pattern balding, and in severe cases even virilization. Sertoli-Leydig Cell Tumors are the most frequent ASN and constitute about 0.5% of all ovarian neoplasms. Typically affecting women under 30 years of age, these tumors are usually unilateral and benign. They are also the most common tumor in postmenopausal women suffering with hyperandrogenism. Other tumors originating from the sex-cord stroma are also known to develop in this population, but the incidence of these is much lower. Approaching suspected hyperandrogenemia and its related symptoms in a clinical setting can be a significant diagnostic challenge. When evaluating a patient for hyperandrogenism, it is important to assess the severity of symptoms but most of all it is critical to assess the time of onset and dynamics of symptom progression. Diagnostic tools including laboratory tests and imaging studies should also be engaged. When deriving a differential diagnosis for androgen-secreting ovarian tumors, adrenal gland tumors should be considered as well as typical endocrine pathologies including polycystic ovary syndrome, congenital adrenal hyperplasia, Cushing's disease, and acromegaly. Treatment options for an androgen-secreting ovarian tumors is mainly surgical, but in exceptional cases can involve pharmacotherapy alone.

Diagnostic utility of a conventional MRI-based analysis and texture analysis for discriminating between ovarian thecoma-fibroma groups and ovarian granulosa cell tumors. J Ovarian Res 2022; 15:65. [PMID: 35610706 PMCID: PMC9131674 DOI: 10.1186/s13048-022-00989-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Accepted: 04/25/2022] [Indexed: 11/24/2022] Open
Abstract
Objective To evaluate the diagnostic utility of conventional magnetic resonance imaging (MRI)-based characteristics and a texture analysis (TA) for discriminating between ovarian thecoma-fibroma groups (OTFGs) and ovarian granulosa cell tumors (OGCTs). Methods This retrospective multicenter study enrolled 52 patients with 32 OGCTs and 21 OTFGs, which were dissected and pathologically diagnosed between January 2008 and December 2019. MRI-based features (MBFs) and texture features (TFs) were evaluated and compared between OTFGs and OGCTs. A least absolute shrinkage and selection operator (LASSO) regression analysis was performed to select features and construct the discriminating model. ROC analyses were conducted on MBFs, TFs, and their combination to discriminate between the two diseases. Results We selected 3 features with the highest absolute value of the LASSO regression coefficient for each model: the apparent diffusion coefficient (ADC), peripheral cystic area, and contrast enhancement in the venous phase (VCE) for the MRI-based model; the 10th percentile, difference variance, and maximal correlation coefficient for the TA-based model; and ADC, VCE, and the difference variance for the combination model. The areas under the curves of the constructed models were 0.938, 0.817, and 0.941, respectively. The diagnostic performance of the MRI-based and combination models was similar (p = 0.38), but significantly better than that of the TA-based model (p < 0.05). Conclusions The conventional MRI-based analysis has potential as a method to differentiate OTFGs from OGCTs. TA did not appear to be of any additional benefit. Further studies are needed on the use of these methods for a preoperative differential diagnosis of these two diseases.

Abstract
Objective This study aims to explore the value of magnetic resonance imaging (MRI) and texture analysis (TA) in the differential diagnosis of ovarian granulosa cell tumors (OGCTs) and thecoma-fibrothecoma (OTCA–FTCA). Methods The preoperative MRI data of 32 patients with OTCA–FTCA and 14 patients with OGCTs, confirmed by pathological examination between June 2013 and August 2020, were retrospectively analyzed. The texture data of three-dimensional MRI scans based on T2-weighted imaging and clinical and conventional MRI features were analyzed and compared between tumor types. The Mann–Whitney U-test, χ2 test/Fisher exact test, and multivariate logistic regression analysis were used to identify differences between the OTCA–FTCA and OGCTs groups. A regression model was established by using binary logistic regression analysis, and receiver operating characteristic curve analysis was carried out to evaluate diagnostic efficiency. Results A multivariate analysis of the imaging-based features combined with TA revealed that intratumoral hemorrhage (OR = 0.037), log-sigma-20mm-3D_glszm_SmallAreaEmphasis (OR = 4.40), and log-sigma-2-0mm-3D_glszm_SmallAreaHighGrayLevelEmphasis (OR = 1.034) were independent features for discriminating between OGCTs and OTCA–FTCA (P < 0.05). An imaging-based diagnosis model, TA-based model, and combination model were established. The areas under the curve of the three models in predicting OGCTs and OTCA–FTCA were 0.935, 0.944, and 0.969, respectively; the sensitivities were 93.75, 93.75, and 96.87%, respectively; and the specificities were 85.71, 92.86, and 92.86%, respectively. The DeLong test indicated that the combination model had the highest predictive efficiency (P < 0.05), with no significant difference among the three models in differentiating between OGCTs and OTCA–FTCA (P > 0.05). Conclusions Compared with OTCA–FTCA, intratumoral hemorrhage may be characteristic MR imaging features with OGCTs. Texture features can reflect the microheterogeneity of OGCTs and OTCA–FTCA. MRI signs and texture features can help differentiate between OGCTs and OTCA–FTCA and provide a more comprehensive and accurate basis for clinical treatment.

Abstract
The approach to hyperandrogenism in women varies depending on the woman's age and severity of symptoms. Once tumorous hyperandrogenism is excluded, the most common cause is PCOS. Hirsutism is the most common presenting symptom. The woman's concern about her symptoms plays an important role in the management of disease. Although measurement of testosterone is useful in identifying an underlying cause, care must be taken when interpreting the less accurate assays that are available commercially. Surgical resection is curative in tumorous etiologies, whereas medical management is the mainstay for non-tumorous causes.

Abstract
PURPOSE To survey the occurrence rate of ascites in patients with thecoma-fibroma and its potential correlation with tumor MR imaging characteristics. METHODS A total of 40 patients with surgically proven thecoma-fibroma were enrolled in this retrospective study. We determined the tumor size, the components (solid or cystic) and their signal intensity features. Second, we identified ascites according to the fat-suppressed sagittal T2-weighted imaging sequence and divided all cases into two groups (with or without ascites). Furthermore, we explored the correlations of ascites with tumor size, tumor solidity, pathological types, patient's postmenopausal status and serum CA-125 levels by using the χ2 test. RESULTS (1) Among the 40 cases, 15 tumors were fibromas, 15 thecomas, and 10 fibrothecomas. Nine patients (26.47%) had elevated CA-125 levels (>35.0 U/ml). (2) Thirty-one patients had ascites (77.50%), 29 of which had a small amount of ascites. Nine cases had no ascites (22.50%). (3) MRI showed a solid mass in 22 cases (55.0%), cystic mass in five cases (12.5%) and mixed solid-cystic mass in 13 cases (32.5%). The χ2 test revealed that the incidence of ascites was significantly correlated with tumor size, tumor solidity and serum CA-125 levels (P < 0.05), but not with menopause and pathological type (P > 0.05). CONCLUSION Our data revealed that the incidence of ascites was 77.50% and was mainly correlated with tumor size and elevated CA-125 levels. These findings have potential value for improving the diagnosis and differential diagnosis of thecoma-fibroma.

Coincidence of juvenile granulosa cell tumor and serous cystadenoma in a pediatric patient: Case report and literature review. Radiol Case Rep 2021; 16:2370-2375. [PMID: 34306284 PMCID: PMC8258790 DOI: 10.1016/j.radcr.2021.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2021] [Revised: 06/04/2021] [Accepted: 06/06/2021] [Indexed: 11/18/2022] Open
Abstract
Juvenile granulosa cell tumor (GCT) is a rare ovarian tumor in children, presenting with a multiloculated cystic pattern and irregular wall-thickening on imaging and serous cystadenoma (SCA) is also another rare benign cystic ovarian tumor in children. The appearance of two uncommon types of ovarian tumors on both sides in children is extremely rare. We report the case of a 4-year-old female presenting with symptoms of precocious puberty and diagnosed with juvenile GCT on the left ovary after surgical resection. However, during follow-up 1 year after GCT resection, she presented with another multiloculated cystic mass in the right ovary, and diagnosed as SCA after surgical resection and histopathologic evaluations. The appearance of cystic ovarian tumor after primarily GCT resection need to differentiate between the recurrence of the primarily GCT and other cystic ovarian tumors although it is very uncommon. Furthermore, the imaging features played a key role in the differential diagnosis between benign and malignant ovarian tumors.

Abstract
BACKGROUND Ovarian sex cord stromal tumours (OSCSTs) are rare ovarian tumours and include different histopathologic subtypes. This study aimed to analyse the clinical and sonographic characteristics of different histopathologic OSCST subtypes. METHODS A total of 63 patients with surgically proven OSCSTs were enrolled in this retrospective study to analyse their clinical and sonographic features. Ultrasound examinations and predictive models were performed before surgery. The clinical and sonographic findings were compared according to the type of OSCST based on the histopathological diagnosis. RESULTS The mean age of 63 patients was 52.17 years (range: 17-78 years). Eighteen patients experienced irregular vaginal bleeding (28.57% 18/63), 7 patients exhibited abnormal body hair (11.11%). 2 patients (3.17%) showed an increased level of CA125, and 25 patients (39.68%, 25/63) showed an increased level of testosterone. Forty-two patients had ovarian thecoma-fibroma groups (OTFGs). Six patients had Sertoli-Leydig cell tumours (S-LCTs), 4 patients had Leydig cell tumours (LCTs), 8 patients had ovarian granulosa cell tumours (OGCTs), 2 patients had ovarian steroid cell tumours, not otherwise specified (OSCTs-NOS), and one patient had sclerosing stromal tumours (SSTs). The mean diameter of the tumour was 47.9 mm (range: 10-258 mm). Forty-seven masses were hypoechoic (74.60%). Twenty-eight masses had posterior echo attenuation, 22 masses exhibited abundant Doppler flow signals (34.92%), and one patient had ascites (1.59%). The diagnostic accuracy of the Simple Rules (SR) and the Assessment of Different NEoplasias in the adneXa (ADNEX) model in distinguishing benign and malignant OSCSTs was 44% (30/63) and 84% (53/63), respectively. The diagnostic accuracy of the SR for OTFGs, S-LCTs & LCTs & OSCTs-NOS, OGCTs, and SSTs was 47.6% (20/42), 16.67% (2/12), 100% (8/8), and 0% (0/1), respectively. The diagnostic accuracy of the ADNEX model for OTFGs, S-LCTs & LCTs & OSCTs-NOS, OGCTs, and SSTs was 93% (31/42), 58.33% (7/12), 75% (6/8), and 100% (1/1), respectively. CONCLUSIONS OSCSTs generally appear as a solid mass on ultrasound. Posterior echo attenuation indicates an OTFG. A solid mass with abundant Doppler flow signals indicates an S-LCT, LCT, OSCT-NOS or OGCT. Current predictive models are not very effective, but symptoms, sonographic features and serum hormones are helpful for diagnosis.

Abstract
Sex cord-stromal tumors of the ovary (SCST) are uncommon ovarian tumors arising from sex cord and/or stromal cells of the ovaries. They may be nonfunctional and asymptomatic or functional presenting with hyperestrogenic, hyperandrogenic or cushingoid symptoms. They present in a wide age group of women, mostly in early stages and follow a nonaggressive clinical course after surgical resection. They differ from more prevalent epithelial ovarian tumors which tend to present in older women in advanced stages with poor prognosis. Some of SCSTs are associated with clinical syndromes. We will review imaging features on ultrasound, computed tomography and magnetic resonance imaging, epidemiology and clinical presentations of these tumors.

Abstract
Objective The aim of the study was to characterize magnetic resonance imaging findings in patients with recurrent ovarian adult granulosa cell tumors (AGCTs). Methods Clinical and magnetic resonance imaging manifestations of recurrent AGCTs were evaluated in 11 patients. Results Initial recurrences of AGCT were diagnosed between 13 months and 30 years (mean, 11.3 years). Recurrent tumors were located in the pelvic peritoneum, the abdominal peritoneum, the retroperitoneum, and bone. The number of recurrent tumors varied from 1 to 5. Tumors varied in morphology and all margins were well circumscribed. The internal structures noted were as follows: multilocular cystic and solid and cystic. Furthermore, internal hemorrhage and sponge-like multicystic components were identified. Conclusions Ovarian AGCTs recurred in the pelvic peritoneum, abdominal peritoneum, and the retroperitoneal lymph nodes. Large recurrent AGCTs were commonly well circumscribed, round or lobulated, and multilocular cystic or solid and cystic. Moreover, they frequently included internal hemorrhage and sponge-like multicystic components.

Abstract
Objective Hirsutism and hyperandrogenism in premenopausal women are most often associated with polycystic ovarian syndrome. We present a case of progressive, severe hyperandrogenism with negative imaging identified on surgical histopathology as being due to a Leydig cell tumor (LCT), thus illustrating localization challenges associated with these small tumors. Methods Laboratory investigations included testosterone, dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone, 24-hour urine cortisol, and prolactin. Imaging included pelvic ultrasound, adrenal magnetic resonance imaging, and computed tomography. Ovarian vein sampling was not available. Results A 42-year-old woman presented with frontal alopecia, voice deepening, coarse facial hair, and amenorrhea on a background of lifelong oligomenorrhea. Peak testosterone was 30.2 nmol/L (female normal range is <2.0 nmol/L) with normal dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, prolactin, 24-hour urine cortisol, and thyroid-stimulating hormone. Transvaginal ultrasound, adrenal magnetic resonance imaging, and computed tomography of the thorax and abdomen revealed no androgen source. Testosterone failed to suppress with gonadotropin-releasing hormone agonist. Although no abnormality was seen during oophorectomy, surgical pathology documented a 1.8-cm, well-circumscribed hilar LCT. Postoperative testosterone was <0.5 nmol/L. Conclusion Although this patient had testosterone levels well into the masculine range, multiple imaging results were negative with a LCT found only after oophorectomy. LCTs are rare ovarian stromal tumors and while 50 to 70% of these tumors produce androgen, size and clinical severity may not be well correlated. This case report illustrates that despite an association with substantially elevated androgen levels, the small size of LCTs can result in localization challenges.

Abstract
Ovarian solid tumors have variable histological types including benign and malignant tumors. In addition, non-neoplastic lesions sometimes show a tumor-like appearance. It is important to differentiate benign from malignant tumors. In general, low signal intensity (SI) on T2-weighted imaging (T2WI), low SI on diffusion-weighted imaging (DWI), and gradual increased pattern on dynamic contrast-enhanced magnetic resonance (MR) imaging are known to be suggestive of a benign tumor. Conversely, there are some cases in which these rules do not apply. We should, therefore, strive for a greater understanding of these exceptional cases. Several tumors show characteristic findings on MR imaging reflecting pathologic features, which leads to the correct diagnosis. Additionally, MR imaging provides important information other than the nature of tumors, such as secondary uterine changes. Furthermore, clinical findings and laboratory examination data also help in determining the correct diagnosis.

Abstract
The spectrum of ovarian tumors in the pediatric population differs significantly from that in adults. Germ cell tumors are the predominant class of ovarian tumors in children, whereas epithelial tumors are the most common in adults. Ultrasonography is the modality of choice for the initial evaluation of pediatric ovarian tumors. Determining the diagnosis based on imaging may prove difficult, and combining the imaging findings with the clinical scenario is very helpful in reaching a differential diagnosis during clinical practice. We will discuss the spectrum of ovarian neoplasms in the pediatric population and describe their clinical, pathologic, and imaging characteristics. A few unique entities related to ovarian tumors, such as growing teratoma syndrome, anti-N-methyl-D-aspartate receptor encephalitis, and hereditary ovarian tumor syndromes, are also discussed. In addition, we will review several entities that may mimic ovarian neoplasms as well as their distinct imaging features.

Abstract
Background To investigate MRI for differentiating benign from malignant sex cord-stromal tumors of the ovary (SCSTs) emphasizing on the value of diffusion-weighted (DW) magnetic resonance (MR) imaging. Methods This retrospective study included 29 benign SCSTs in 28 patients and 13 malignant SCSTs in 13 patients. DW imaging as well as conventional MR imaging was performed. Signal intensity on DW imaging was assessed and apparent diffusion coefficient (ADC) value was measured. In addition, T2 signal intensity and contrast enhancement pattern were also assessed and compared between benign and malignant SCSTs. Results Both of the T2 hypointensity and mild enhancement were specific to benign SCSTs. The majority of malignant SCSTs showed high signal intensity on DW imaging, whereas most benign SCSTs showed low or moderate signal intensity (p = 0.000). Fibromas were the tumors with the lowest observed ADC value (0.470 × 10− 3 mm2/s). Sclerosing stromal tumors were the tumors with the highest observed ADC value (2.291 × 10− 3 mm2/s). ADC value of solid component was significantly lower in malignant SCSTs (0.825 ± 0.129 × 10− 3 mm2/s) than in benign SCSTs (1.343 ± 0.528 × 10− 3 mm2/s) when fibromas were excluded (p = 0.024). T2, DCE and DW imaging has a limited value on the differential diagnosis of the benign and malignant SCSTs with an accuracy of 69.0%,71.4% and 78.1% respectively. Combination of T2, DCE and DW imaging permitted the distinction with an accuracy of 88.0%. Conclusions It is more helpful for distinction of the benign and malignant SCSTs by combining of T2, DCE and DW imaging than using each of the three sequences independently.

Abstract
Our report details the workup and management of a 43-year-old woman with an identical twin who presented with 2 years of virilization and secondary amenorrhea. Serum total testosterone was elevated. An MRI did not identify adnexal or adrenal pathology. Subsequent ovarian vein sampling demonstrated unilateral testosterone elevation. The patient underwent laparoscopic unilateral oophorectomy resulting in the diagnosis of Sertoli-Leydig cell tumor (SLCT). Although SLCT is a rare sex-cord ovarian tumor, it is associated with endometrial hyperplasia and malignancy. Our goals are to review the workup of androgen-secreting tumors and discuss the clinical importance of the DICER1 mutation in the context of SLCT. In this case, an identical twin underwent DICER1 testing which was one of the essential steps in her clinical management.

Abstract
BACKGROUND To describe magnetic resonance imaging (MRI) features of ovarian granulosa cell tumors (OGCTs) and compare with other sex cord-stromal tumors (OSCs) in ovary. METHODS MR findings of 18 patients with surgically confirmed ovarian granulosa cell tumor were retrospectively reviewed by two radiologists with consensus reading. All MR examinations were prospectively performed within one month. Clinical and imaging characteristics of OGCTs were evaluated and compared with OSCs (control group). RESULTS In 18 patients, 20 ovarian granulosa cell tumors were detected on MRI. Sixteen tumors appeared as solid or mostly solid mass (16/20), while 4 tumors as cystic mass. Pathological pelvic fluid was detected in 1 OGCT (1/18) and 11 OSCs (11/34) (p = 0.031).On T2 weighted imaging (T2WI), most of OGCTs displayed hyperintense signal and mixed signal (19/20); on T1 weighted imaging (T1WI), 11 OGCTs (11/20) displayed similar signal as on T2WI imaging. The lesion signal between OGCT and OSC differed significantly on both T1WI (p = 0.017) and T2WI (p = 0.002). Tumoral bleeding was detected in 6 OGCTs on MRI. On diffusion weighted imaging (DWI) images, OGCTs mostly appeared as high signal (16/20). Average apparent diffusion coefficient (ADC) value derived from DWI images in the OGCT group (0.84 ± 0.26× 10- 3 mm2/s was less than the control group (1.22 ± 0.47 × 10- 3 mm2/s) with statistical difference (p = 0.002). CONCLUSIONS MRI could provide important information in OGCT diagnosis. ADC value might be useful in differentiating OGCT from OSC.

Abstract
RATIONALE The incidence of severe hyperandrogenism associated with masculinity in women is very low. While rare and difficult to diagnose, androgen secreting tumors should be suspected in women with hyperandrogenism and hirsutism, especially in the postmenopausal population. Herein we present one case of ovarian Leydig cell tumor (LCT) with markedly elevated serum testosterone levels and frank hirsutism. PATIENT CONCERNS A 60-year-old woman, presented with increased hair growth and androgenic alopecia and the hormonal laboratory examination showed that she had elevated serum testosterone level and normal dehydroepiandrosterone sulfate (DHEAS), androstenedione, 17- hydroxyprogesterone, cortisol and thyroid stimulating hormone (TSH). DIAGNOSES The diagnosis of possible testosterone secreting tumor was performed when pelvic computed tomography (CT) and magnetic resonance image (MRI) showed a right adnexal mass of 15mm×16mm indicative of sex cord- stromal tumors. INTERVENTIONS The patient received laparoscopic total abdominal hysterectomy and bilateral salpingo-oophorectomy. OUTCOMES After operation, testosterone got back to the normal level and clinical symptoms subsided. LESSONS It is common that postmenopausal androgen excess is a state of relative or absolute androgen excess originating from the adrenal gland and/or ovaries. In either case, doctors need to assess such patients and exclude relatively rare potential causes of tumors. Any woman who has hirsutism or frank evidence of markedly increased testosterone should exclude this kind of possibility of androgen producing tumors. It is possible to determine the origin of androgen hypersecretion with the severity of symptoms, the extent of androgen excess, and the relevant imaging studies. Since LCT are rare ovarian sex-cord stromal tumors, it can be beneficial for diagnosis with careful research of patient history of the defeminization followed by virilization, and a CT and MRI image.

Abstract
The aim of the present study was to investigate the imaging characteristics of ovarian fibrothecoma. The cases of 25 female patients with pathologically confirmed ovarian fibrothecomas were retrospectively reviewed. Tumor location, size, density, signal intensity, cystic degeneration, calcification, enhancement pattern and ascites were assessed by computed tomography (CT) (n=20) and magnetic resonance imaging (MRI) (n=5). Clinical and histological features were also evaluated. The results revealed that 23 (92.0%) patients were postmenopausal, with a mean age ± standard deviation (SD) of 60.7±10.8 years old. All 25 tumors were unilateral and a thickened endometrium was observed in 7 (28.0%) patients. In total, 24 (96.0%) tumors appeared to have well-defined boundaries, with 1 (4%) tumor exhibiting an obscure boundary. Tumors had a mean size of 9.8±5.3 cm. Solid and predominantly solid masses were found in 16 cases (64.0%), and cystic and predominantly cystic masses were found in 9 patients (36.0%). Solid regions of masses exhibited hypodensity or isodensity in 24 patients (96.0%), with 1 patient (4.0%) exhibiting hyperdensity. The mean CT value (± SD) was 44.2±12.8 HU (range, 31-79HU) in unenhanced images. All masses exhibited isointensity or slight hypointensity on T1-weighted imaging, and tumor parenchyma also exhibited slight hypointensity or isointensity on T2-weighted imaging compared with the myometrium, with or without areas of patchy hyperintensity. Contrast-enhanced CT or MRI scans were performed on 19 patients, and the solid components (94.7%) exhibited mild to moderate enhancement in 18 patients and 1 patient (5.3%) exhibited intense enhancement. Tumor size was positively correlated with the tumor cystic degeneration (r=0.77, P<0.001) and ascites (r=0.41, P<0.001). Therefore, ovarian fibrothecoma typically presents as solid or predominant solid masses with clear boundaries; the parenchyma of the tumor exhibits isodensity on CT scans, slight hypointensity or isointensity on MRI and mild enhancement following contrast-medium injection. The thickened endometrium observed in postmenopausal woman may also be a valuable imaging feature.

Abstract
Ovarian sex cord-stromal tumors are infrequent and represent approximately 7% of all primary ovarian tumors. This histopathologic ovarian tumor group differs considerably from the more prevalent epithelial ovarian tumors. Although sex cord-stromal tumors present in a broad age group, the majority tend to present as a low-grade disease that usually follows a nonaggressive clinical course in younger patients. Furthermore, because the constituent cells of these tumors are engaged in ovarian steroid hormone production (e.g., androgens, estrogens, and corticoids), sex cord-stromal tumors are commonly associated with various hormone-mediated syndromes and exhibit a wide spectrum of clinical features ranging from hyperandrogenic virilizing states to hyperestrogenic manifestations. The World Health Organization sex cord-stromal tumor classification has recently been revised, and currently these tumors have been regrouped into the following clinicopathologic entities: pure stromal tumors, pure sex cord tumors, and mixed sex cord-stromal tumors. Moreover, some entities considered in the former classification (e.g., stromal luteoma, stromal tumor with minor sex cord elements, and gynandroblastoma) are no longer considered separate tumors in the current classification. Herein, we discuss and revise the ultrasonography, computed tomography, and magnetic resonance imaging characteristics of the different histopathologic types and clinicopathologic features of sex cord-stromal tumors to allow radiologists to narrow the differential diagnosis when facing ovarian tumors.

Abstract
We report a 70-year-old female presenting with increased libido and mild but rapid onset virilism. Investigations showed markedly elevated androstenedione and 17 hydroxyprogesterone misdirecting to possible late-onset congenital adrenal hyperplasia. High serum testosterone and oestrogens with suppressed gonadotrophins, however, indicated an androgen-secreting tumour. A normal dehydroepiandrosterone sulphate and elevated inhibins A and B indicated the tumour was ovarian in origin, which was confirmed on pelvic examination and imaging. At laparotomy, a right ovarian sertoliform endometrioid carcinoma was removed, following which the patient developed menopausal vasomotor symptoms and improvement of her virilism. Serum testosterone, oestradiol, inhibins A and B became undetectable, gonadotrophins appropriately increased and 17 hydroxyprogesterone and androstenedione normalized. We propose that inhibins may be of diagnostic value and should be included in investigative algorithms of females with virilization and hyperandrogenaemia, especially if postmenopausal. Androgen-secreting tumours must be excluded before raised 17 hydroxyprogesterone concentrations are used to diagnose late-onset congenital adrenal hyperplasia in females with new-onset virilization.

Abstract
Transabdominal US remains the primary screening imaging modality of the pediatric female pelvis. However, MRI has become an invaluable adjunct to US in recent years. MRI offers superb soft-tissue contrast resolution that allows for detailed evaluation, particularly of the ovaries and their associated pathology. MRI can yield diagnostic information that is similar to or even better than that of US, especially in nonsexually active girls in whom transvaginal US would be contraindicated. MRI is generally a second-line examination and is preferred over CT because it does not involve the use of ionizing radiation. MRI might be underutilized in this population, particularly in differentiating surgical from nonsurgical conditions. This article reviews the relevant anatomy and discusses imaging of acquired conditions that involve the pediatric female genital tract, illustrating associated pathology with case examples.

Abstract
OBJECTIVE We propose a Magnetic Resonance Imaging (MRI) guided approach to differential diagnosis of ovarian tumours based on morphological appearance. BACKGROUND Characterization of ovarian lesions is of great importance in order to plan adequate therapeutic procedures, and may influence patient's management. Optimal assessment of adnexal masses requires a multidisciplinary approach, based on physical examination, laboratory tests and imaging techniques. Primary ovarian tumours can be classified into three main categories according to tumour origin: epithelial, germ cell and sex cord-stromal tumours. Ovarian neoplasms may be benign, borderline or malignant. Using an imaging-guided approach based on morphological appearance, we classified adnexal masses into four main groups: unilocular cyst, multilocular cyst, cystic and solid, predominantly solid. We describe MR signal intensity features and enhancement behaviour of ovarian lesions using pathologically proven examples from our institution. CONCLUSION MRI is an essential problem-solving tool to determine the site of origin of a pelvic mass, to characterize an adnexal mass, and to detect local invasion. The main advantages of MRI are the high contrast resolution and lack of ionizing radiation exposure. Although different pathological conditions may show similar radiologic manifestations, radiologists should be aware of MRI features of ovarian lesions that may orientate differential diagnosis. TEACHING POINTS • Diagnostic imaging plays a crucial role in detection, characterization and staging of adnexal masses. • Characterization of an ovarian lesion may influence patient's management. • Different pathological conditions may have similar radiologic manifestations. • Non-neoplastic lesions should always be taken into consideration.

Abstract
Background Our study aims to determine the value of diffusion-weighted imaging (DWI) combined with conventional magnetic resonance imaging (MRI) in the diagnosis of thecomas/fibrothecomas and their differential diagnosis with malignant pelvic solid tumors. Methods In total, 36 thecomas/fibrothecomas and 40 malignant pelvic solid tumors were included in our study. All patients underwent 1.5 T conventional MRI and DWI examinations except one patient with a fibrothecoma in whom DWI examination was not performed. The clinical features and characteristics of conventional MRI and DWI of these two groups were analyzed. Apparent diffusion coefficient (ADC) values were measured and compared between groups. Univariate analysis, multivariate logistic regression analysis, and the receiver operating characteristic curve were used for statistical analysis. Results All the thecomas/fibrothecomas showed isointensity on T1 weighted imaging (T1WI) and 77.8 % (28/36) lesions showed hypo- to isointensity on T2 weighted imaging (T2WI). After administration of contrast medium, 94.4 % (34/36) tumors appeared as minor to mild enhancement. On DWI, they showed a diversity of low to very high signal intensity. All malignant pelvic masses manifested as hyperintensity on T2WI and 87.5 % (35/40) tumors showed very high signal (grade 3) on DWI. Higher area under the curve (AUC) and specificity could be achieved by using the lowest ADC value than the mean ADC value. Multivariate logistic regression analysis showed that shape, signal intensity on T2WI, capsule, and the lowest ADC value were the important indicators in discriminating thecomas/fibrothecomas from malignant pelvic solid tumors. Conclusions The combination of DWI and conventional MRI is of great value in the diagnosis of thecomas/fibrothecomas and their differential diagnosis with malignant pelvic solid tumors.

Abstract
Complex solid and multicystic ovarian lesions are broad-spectrum diseases, ranging from benign to malignant. This article describes the broad-spectrum and imaging features of complex solid and multicystic ovarian lesions and illustrates an algorithmic approach to such lesions, focusing on the ultrasonography and magnetic resonance imaging features that allow one to hone the differential diagnosis. Multimodality imaging workup plays an important role in the characterization and differential diagnosis of these diseases. Also, knowledge of the clinical setting and imaging features for the spectrum of complex solid and multicystic ovarian lesions can lead to appropriate management.

Abstract
Les tumeurs non épithéliales malignes de l'ovaire représentent environ 20% des cancers de l'ovaire. L'objectif de notre travail est de dresser les particularités diagnostiques cliniques et d'imagerie de ces tumeurs. Nous avons procédé à une étude rétrospective portant sur 11 cas de tumeurs non épithéliales de l'ovaire. Ces tumeurs ont été colligées au service de gynécologie et obstétrique I du CHU Hassan II de Fès sur une période de 4 ans, entre janvier 2009 et décembre 2012. Les tumeurs germinales représentant 54% (6 patientes) des cas alors que les tumeurs du cordon sexuel ont été représentées par 4 cas de tumeurs de granulosa de type adulte et nous avons colligés un cas de lymphome ovarien primitif. La symptomatologie clinique était dominée par la distension abdominale associée souvent à des douleurs abdominopelviennes chroniques. La taille tumorale moyenne était de 175 mm avec un aspect solido-kystique dans 54% des cas. Le dosage des marqueurs tumoraux (hormone chorionique gonadotrope, lactate déshydrogénase, CA 125, alpha-fœtoprotéine) a été réalisé chez toutes les patientes. La découverte d'une masse annexielle suspecte chez une jeune femme doit, outre une tumeur frontière ou un cancer épithélial de l'ovaire, évoquer une tumeur non épithéliale, a fortiori si cette masse est volumineuse, si elle est associée à des signes d'hyperestrogénie ou d'androgénie.

Abstract
Here we describe the case of a 19-year-old woman with a poorly differentiated ovarian Sertoli-Leydig cell tumor and an elevated serum alpha-fetoprotein level. The patient presented with diffuse abdominal pain and bloating. Physical examination, ultrasound, and magnetic resonance imaging revealed a right ovarian tumor that was histopathologically diagnosed as a poorly differentiated Sertoli-Leydig cell tumor with heterologous elements. Her alpha-fetoprotein serum level was undetectable after tumor resection. Sertoli-Leydig cell tumors are rare sex cord-stromal tumors that account for 0.5% of all ovarian neoplasms. Sertoli-Leydig cell tumors tend to be unilateral and occur in women under 30 years of age. Although they are the most common virilizing tumor of the ovary, about 60% are endocrine-inactive tumors. Elevated serum levels of alpha-fetoprotein are rarely associated with Sertoli-Leydig cell tumors, with only approximately 30 such cases previously reported in the literature. The differential diagnosis should include common alpha-fetoprotein-producing ovarian entities such as germ cell tumors, as well as other non-germ cell tumors that have been rarely reported to produce this tumor marker.

Abstract
OBJECTIVE Female pelvic masses have a broad differential diagnosis, including benign and malignant neoplasms and nonneoplastic entities. CONCLUSION By using a systematic approach to the evaluation of a complex pelvic mass, including incorporating the clinical and surgical history, and by using multiparametric MRI to identify the anatomic origin, morphologic features, and tissue composition of a mass, a short meaningful differential diagnosis or definitive diagnosis can often be established.

Abstract
Solid adnexal masses, while less common than their cystic counterparts, may present a challenge for radiologists given the wide range of histologic entities that occur in this region. Pelvic masses, especially when large, can seem overwhelming at first but application of an algorithmic approach allows for more confident assessment. This approach focuses first on the use of anatomic relationships and interactions of various pelvic structures to localize the mass' origin. For instance, the directionality of ureteral displacement can suggest if a mass is intra or extraperitoneal. Then, key discriminating imaging features, such as the presence of fat, hypervascularity, or low T2 signal on magnetic resonance imaging (MRI) can be applied to further narrow the list of diagnostic possibilities. Entities such as leiomyomas, nerve sheath tumors, congenital uterine anomalies, and vascular abnormalities (ovarian torsion or iliac vessel aneurysm) in particular are often accurately characterized with sonography and/or MRI. For solid adnexal masses in which a definitive diagnosis by imaging is not reached, information germane to clinicians regarding further management can still be provided, principally with regard to surgical vs. nonsurgical treatment.

Abstract
A 7-year-old Indian girl presented with symptoms of excessive development of breasts, early menarche, growth of pubic hairs, accelerated growth and abdominal distension. On clinical examination, a large right abdominopelvic mass was palpable. MRI revealed a large, heterogeneous, solid and cystic tumour in the right adnexal region, suggestive of an ovarian neoplasm. The hormonal profile showed markedly elevated oestradiol and low follicle-stimulating hormone levels. Clinical diagnosis of precocious puberty with right ovarian mass was concluded. Right-sided salpingo-oophorectomy was performed. Histopathology showed features consistent with sclerosing stromal tumour of the ovary. Postoperatively, signs and symptoms of precocity gradually regressed and her serum oestradiol level came down to normal. This is the first reported case from India.

Abstract
OBJECTIVE To study MRI diagnosis of ovarian fibrothecomas. METHODS MRI appearances of 27 ovarian fibrothecomas 26 female patients confirmed by surgical pathology were retrospectively reviewed and correlated with clinical and histological findings. RESULTS Most patients were post-menopausal females 73.1% (19/26) of cases. 38.5% (10/26) of patients showed an elevated serum carbohydrate antigen 125 (CA-125) level (>35 U ml(-1)). On MR T2 weighted imaging, 3 distinct features were revealed. (1) Homogeneous hypointense masses in 25.9% (7/27) cases. (2) Heterogeneous tumours with mostly isointense and few patchy hyperintense areas in 51.9% (14/27) cases. (3) Heterogeneous tumours with predominantly hyperintense and few isointense parts in 22.2% (6/27) cases. On T1 weighted imaging, all the fibrothecomas turned out to be homogeneous masses except six cystic degeneration cases. After contrast, 70.4% (19/27) tumours showed homogeneous mild enhancement in all phases. Beyond the tumours, endometrial abnormality and uterus enlargement were found in 38.5% (10/26) and 15.4% (4/26) patients, respectively. Ascites were seen in 53.8% (14/26) patients. There was a statistically significant difference among the 3 T2 weighted image features (F = 7.024; p = 0.003) in terms of the size of fibrothecomas. The cystic tumours also had the tendency to show the ascite condition (p = 0.002) as well as elevated serum CA-125 levels (p = 0.014). Vimentin was positively stained in 10 (76.9%) of 13 cases who underwent the immunohistochemical analysis. CONCLUSION MRI has the superiority to show the distinct appearances of tumours as well as their functional features according to oestrogenic effect. ADVANCES IN KNOWLEDGE This study describes the unique features of fibrothecomas on MRI on a relatively large series of patients with tumours and the indirect oestrogenic effect findings.

Abstract
Background To investigate the magnetic resonance imaging (MRI) characteristics of ovarian Sertoli-Leydig cell tumors (SLCT). Methods The clinical, MRI and pathological findings of five cases of SLCT were reviewed retrospectively. MRI appearances of tumors including laterality, shape and size, architecture, wall, septa and vegetation, signal intensity and contrast-enhancement pattern were evaluated and correlated with pathological findings. Results Two tumors were solid which appeared as low signal intensity on T1-weighted imaging (T1WI) and moderate on T2-weighted imaging (T2WI) with multiple small cysts in one of them. The remaining three SLCT were multilocular cystic with the irregularly thickened wall and septa, and with solid area and mural nodules in one of them. The cystic components had the same signal intensity as urine. All the solid components were intensely enhanced after administration of contrast medium. All five tumors were pathologically intermediate differentiation and at FIGO stage I. Conclusions SLCT demonstrate variable MRI morphological appearances. However, the irregularly thickened wall and septa, the moderate T2WI signal intensity and obvious enhancement in the solid components are three MRI features.

Abstract
Background To investigate the value of diffusion-weighted imaging (DWI) at 3.0 T (3T), and especially the apparent diffusion coefficient (ADC), in discriminating ovarian thecoma from other adnexal solid masses. Methods Eighteen thecomas or fibrothecomas, 14 ligamentous leiomyomas, and 24 other ovarian solid tumors underwent prospective DWI magnetic resonance imaging (MRI) in addition to routine MRI on a 3T MRI machine. The baseline characteristics, components, and conventional MRI and DWI-MRI signals for the thecomas were recorded. The ADC values (ADCs) were measured for each group and compared. Results The thecomas often appeared as homogeneous isointensity (17/18) on T1-weighted images (T1WI; 11/18) or T2WI (11/18) on DWI-MRI, with minor (9/18) or mild (6/18) enhancement. The mean ADC value for thecoma (1.20 ± 0.45 × 10−3 mm2/s) was almost equal to that of the other solid ovarian masses (1.26 ± 0.51 × 10−3 mm2/s), but lower than that for leiomyoma (1.48 ± 0.42 × 10−3 mm2/s), although not significantly so. There was a significant difference (p = 0.043) in the ADCs of the benign ovarian solid masses (1.16 ± 0.47 × 10−3 mm2/s) and leiomyomas (1.48 ± 0.42 × 10−3 mm2/s). Conclusions There is no significant difference in ADC between thecoma and other adnexal solid masses, but the ADCs of thecomas are lower than those of leiomyomas.

Abstract
OBJECTIVE To analyze the imaging findings of ovarian thecoma and to better understand the tumor features based on aspect of computed tomography and magnetic resonance images. METHODS Nineteen ovarian thecomas confirmed by histopathologic examination were analyzed retrospectively. Image characteristics were analyzed and compared with those of the pathologic features. RESULTS The mean diameter of tumors was 9.6 cm. The masses were well defined (n = 17) or ill defined (n = 2) and appeared solid with cystic areas (n = 11), entirely solid (n = 4), or cystic with solid components (n = 4). On T2-weighted/spectral adiabatic inversion recovery (T2WI/SPAIR) images, 12 cases appeared isointense or slightly hyperintense. Of the 12 cases, 8 had patchy hypersignal areas. On computed tomographic images, 7 cases showed hypodensity or isodensity. All tumors exhibited mild enhancement. On pathologic examination, the tumor was composed of spindle cells with a moderate amount of cytoplasm. CONCLUSION Imaging manifestations of ovarian thecoma are various and nonspecific. However, a large, well-defined mildly enhanced solid mass with cystic areas and especially isointense or slightly hyperintense on T2WI/SPAIR sequence in pelvic cavity may suggest the diagnosis of ovarian thecoma.

Abstract
Ovarian masses present a special diagnostic challenge when imaging findings cannot be categorized into benign or malignant pathology. Ultrasonography (US), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) are currently used to evaluate ovarian tumors. US is the first-line imaging investigation for suspected adnexal masses. Color Doppler US helps the diagnosis identifying vascularized components within the mass. CT is commonly performed in preoperative evaluation of a suspected ovarian malignancy, but it exposes patients to radiation. When US findings are nondiagnostic or equivocal, MRI can be a valuable problem solving tool, useful to give also surgical planning information. MRI is well known to provide accurate information about hemorrhage, fat, and collagen. It is able to identify different types of tissue contained in pelvic masses, distinguishing benign from malignant ovarian tumors. The knowledge of clinical syndromes and MRI features of these conditions is crucial in establishing an accurate diagnosis and determining appropriate treatment. The purpose of this paper is to illustrate MRI findings in neoplastic and non-neoplastic ovarian masses, which were assessed into three groups: cystic, solid, and solid/cystic lesions. MRI criteria for the correct diagnosis and characteristics for differentiating benign from malignant conditions are shown in this paper.

Abstract
We review the clinical and imaging characteristics of the most common ovarian neoplasms in children and adolescents. Because of the widespread use of diagnostic imaging, incidental ovarian neoplasms might be encountered during the evaluation of abdominal pain, trauma or other indications and might pose a diagnostic dilemma. Conducting adequate imaging studies under these conditions is important, as management strategies differ according to the size and appearance of the lesion as well as the age of the patient. US dominates in gynecological imaging because of its excellent visualization, absence of ionizing radiation and sedation risks and comparatively low cost. For further examination of indeterminate lesions found using US, MRI is being used more progressively in this field, particularly for the evaluation of complex pelvic masses with the aim of distinguishing benign and malignant conditions and conditions requiring surgical intervention. CT is reserved primarily for tumor staging and follow-up and for emergency situations.
