Radiology Interpretation

The complex anatomy and similarity of imaging features of various pathologies in the pelvis can make accurate radiology interpretation difficult. While prompt recognition of ovarian cancer remains essential, awareness of processes that mimic ovarian tumors can avoid potential misdiagnosis and unnecessary surgery. This article details the female pelvic anatomy and highlights relevant imaging features that mimic extra-ovarian tumors, to help the radiologists accurately build a differential diagnosis of a lesion occupying the adnexa.

The aim of this work was to compare mean concentrations of gonadotropins in serum and fluid from malignant and benign ovarian tumors. We enrolled 126 patients diagnosed with malignant epithelial tumors (n=40), borderline epithelial tumors (n=14), benign cystadenomas (n=28) and simple cysts (n=44) of the ovary. Premenopausal and postmenopausal subgroups were formed in each group. The concentration of FSH and LH was measured in serum and tumor fluid and the serum/tumor fluid ratio was calculated. The results in each group were compared and the sensitivity, specificity, positive and negative predictive values were determined. Mean concentrations of both gonadotropins in ovarian cancer fluid were significantly higher than in the remaining groups (P ranged from <0.005 to <0.0001). Mean serum/fluid ratios were lowest in ovarian cancer (FSH=2.91, LH=4.19). Our findings support the hypothesis that gonadotropins are involved in ovarian carcinogenesis and suggest that gonadotropin serum/tumor fluid ratios could be of value in the differential diagnosis of functional and organic cysts of the ovary.

This study aimed to assess the potential value of peritoneal fluid cytokine examination for the differential diagnosis of ovarian tumors and for evaluating residual or recurrent disease after treatment. The cytokines that are commonly elevated in ovarian cancer, VEGF, IL-6, bFGF, IL-8 and M-CSF, and a reference ovarian tumor marker, CA 125, were measured in peritoneal fluids of 53 previously untreated patients with epithelial ovarian cancer, 18 ovarian cancer patients after surgical treatment and chemotherapy, and 17 patients with benign epithelial ovarian tumors. Non-parametric statistical analysis of data was performed. Ovarian cancer peritoneal fluids, as compared to peritoneal fluids of patients with benign ovarian tumors, contained significantly higher concentrations of IL-6, VEGF and CA 125, and significantly lower concentrations of bFGF and M-CSF, but only the levels of IL-6 and VEGF were significantly higher in peritoneal fluids of stage I and II ovarian cancer patients than of patients with benign ovarian conditions. IL-6 at the cutoff level of 400 pg/mL discriminated benign and malignant ovarian tumors with 92% sensitivity and 60% specificity, while VEGF at the cutoff of 400 pg/mL had 90% sensitivity and 80% specificity. At the cutoff level of 1200 pg/mL, IL-6 had 84% sensitivity and 87% specificity. A radical decrease in local cytokine and CA 125 levels in patients after treatment was independent of therapy outcome. IL-6 and VEGF measurements in peritoneal fluids might be useful for the differential diagnosis of malignant and benign ovarian conditions, but not for residual or recurrent disease examination.

Abstract Background Abdominal tuberculosis is an uncommon variant of extrapulmonary tuberculosis. It accounts for 3.5% of extrapulmonary tuberculosis. Diagnosis of abdominal tuberculosis is still a challenge due to its non-specific symptoms. Abdominal tuberculosis and ovarian cancer may show similar symptoms, laboratory and imaging features. The goal of our report is to emphasize for the need of a diagnostic approach based on clinical manifestations, laboratory, imaging findings, and additional tests for considering a diagnosis of abdominal tuberculosis rather than ovarian cancer. Case presentation We report 3 cases of abdominal tuberculosis in our Onco-gynaecology Division, Department of Obstetrics and Gynaecology, Sardjito Hospital, Yogyakarta, Indonesia in 2018 which were previously diagnosed as ovarian malignancy and managed surgically. All of our patients experienced abdominal pain and enlargement but only two of them had significant weight loss. The general symptoms were typically found in onco-gynaecology patients, especially in those with ovarian malignancy. Ultrasound examination showed multilocular masses, 2 of them with solid parts and ascites. Cancer antigen 125 (CA-125) levels were found increasing in those three patients. All of them were treated surgically and diagnosis of abdominal tuberculosis was established through the histopathological result of tissue biopsy. Based on our cases and literature, we consider the need of a diagnostic approach to differentiate abdominal tuberculosis from ovarian malignancy, an attempt to avoid unnecessary invasive procedures that put burden risk for the patients. Conclusion Minimally invasive tests to establish the diagnosis of abdominal tuberculosis should be optimized to reduce the burden risk of laparotomy. Careful diagnostic steps should be followed to avoid wrong diagnosis.

Abstract Coronavirus disease-19 (COVID-19) is only one of the many possible infectious and non-infectious diseases that may occur with similar imaging features in patients undergoing [18F]-fluorodeoxyglucose (18FDG) monitoring, particularly in the most fragile oncologic patients. We briefly summarise some key radiological elements of differential diagnosis of interstitial lung diseases which, in our opinion, could be extremely useful for physicians reporting 18FDG PET/CT scans, not only during the COVID-19 pandemic, but also for their normal routine activity.

Extraosseous Ewing’S Sarcoma

AbstractExtraosseous Ewing’s sarcoma (EES), first described in 1969, is a malignant mesenchymal tumor just like its intraosseous counterpart. Although Ewing’s sarcomas are common bone tumors in young children, EESs are rarer and more commonly found in older children/adults, often carrying a poorer prognosis. We discuss the multimodality imaging features of EES and the differential diagnosis of an aggressive appearing mass in proximity to skeletal structures, with pathologic correlates. This review highlights the need to recognize the variability of radiologic findings in EES such as the presence of hemorrhage, rich vascularity, and cystic or necrotic regions and its imaging similarity to other neoplasms that are closely related pathologically.

ObjectiveVaginal hysterectomy with bilateral salpingo-oophorectomy may be an alternative strategy for patients with low-risk endometrial cancer and medical co-morbidities precluding laparoscopic or abdominal procedures. The current study evaluates the prevalence of co-existent ovarian malignancy in patients with endometrial cancer and the influence of bilateral salpingo-oophorectomy on survival outcomes in these patients.MethodsMedline and EMBASE were searched for studies published between January 1, 2000 and November 20, 2017 that investigated (1) the prevalence of co-existing ovarian malignancy (either metastases or primary synchronous ovarian cancer in women with endometrial cancer, and (2) the influence of bilateral salpingo-oophorectomy on recurrence and/or survival rates.ResultsOf the pre-menopausal and post-menopausal patients (n=6059), 373 were identified with metastases and 106 were identified with primary synchronous ovarian cancer. Of the post-menopausal patients (n=6016), 362 were identified with metastases and 44 were identified with primary synchronous ovarian cancer. Survival outcomes did not differ for pre-menopausal patients with endometrial cancer with and without bilateral salpingo-oophorectomy (5-year overall survival rates were 89–94.5% and 86–97.8%, respectively).ConclusionBilateral salpingo-oophorectomy during vaginal hysterectomy seems to have a limited impact on disease outcome in patients with endometrial cancer. These results support the view that vaginal hysterectomy alone or with bilateral salpingo-oophorectomy may be an option for patients with endometrial cancer who are not ideal surgical candidates.

Objective: CA-125 is widely used as biomarker of ovarian cancer. However, CA-125 suffers low accuracy. We developed a hybrid analytical model, the Ovarian Cancer Decision Tree (OCDT), employing a two-layer decision tree, which considers genetic alteration information from cell-free DNA along with CA-125 value to distinguish malignant tumors from benign tumors. Methods: We consider major copy number alterations at whole chromosome and chromosome-arm level as the main feature of our detection model. Fifty-eight patients diagnosed with malignant tumors, 66 with borderline tumors, and 10 with benign tumors were enrolled. Results: Genetic analysis revealed significant arm-level imbalances in most malignant tumors, especially in high-grade serous cancers in which 12 chromosome arms with significant aneuploidy ( P<0.01) were identified, including 7 arms with significant gains and 5 with significant losses. The area under receiver operating characteristic curve (AUC) was 0.8985 for copy number variations analysis, compared to 0.8751 of CA125. The OCDT was generated with a cancerous score (CScore) threshold of 5.18 for the first level, and a CA-125 value of 103.1 for the second level. Our most optimized OCDT model achieved an AUC of 0.975. Conclusions: The results suggested that genetic variations extracted from cfDNA can be combined with CA-125, and together improved the differential diagnosis of malignant from benign ovarian tumors. The model would aid in the pre-operative assessment of women with adnexal masses. Future clinical trials need to be conducted to further evaluate the value of CScore in clinical settings and search for the optimal threshold for malignancy detection.
