OBJECTIVES: International Ovarian Tumor Analysis (IOTA) working group proposed a logistic regression (IOTA LR2) model. It is served as a risk prediction model for benign and malignant adnexal tumors. This study aims to compare the diagnostic efficiency between the IOTA LR2 model and doctors' subjective assessment on diagnosing benign and malignant adnexal mass. METHODS: The ultrasonographic images of 616 adnexal masses were retrospectively analyzed by the senior doctors' group and the junior doctors' group using the IOTA LR2 model and subjective assessment. The postoperative pathological diagnosis was used as the gold standard to compare the diagnostic efficiency of the 2 methods. RESULTS: The area under the curves of subjective assessment and IOTA LR2 model for diagnosing malignant adnexal masses were 0.86 and 0.90 for the senior doctors' group and 0.79 and 0.88 for the junior doctors' group, respectively. The sensitivity and specificity of subjective assessment for diagnosing the malignant adnexal masses were 81.0% and 91.3% for the senior doctors' group and 70.1% and 88.7% for the junior doctors' group, respectively. The sensitivity and specificity of the IOTA LR2 model for diagnosing the malignant adnexal masses were 79.6% and 88.1% for the senior doctors' group, and 79.6% and 81.7% for the junior doctors' group, respectively.There were no significant difference in the sensitivities between the senior doctors' group and junior doctors' group using the IOTA LR2 model and the senior doctors' group using subjective assessment (both P>0.05). CONCLUSIONS The diagnostic efficiency of the IOTA LR2 model is equal to the senior doctors' experiences. This model can help junior doctors to reduce the missed diagnosis of malignant adnexal masses.

OBJECTIVE: To explore the in-vivo 1H- MR spectral features of adnexal lesions and to characterize the spectral patterns of various pathologic entities. MATERIALS AND METHODS: Thirty-one patients with surgically and histopathologically confirmed adnexal lesions underwent short echo-time STEAM (stimulated echo acquisition method) 1H- MR spectroscopy, and the results obtained were analysed. RESULTS: The methylene present in fatty acid chains gave rise to a lipid peak of 1.3 ppm in the 1H- MR spectra of most malignant tumors and benign teratomas. This same peak was not observed, however, in the spectra of benign ovarian epithelial tumors: in a number of these, a peak of 5.2 ppm, due to the presence of the olefine group (-CH=CH-) was noted. The ratios of lipid peak at 1.3 ppm to water peak (lipid/water ratios) varied between disease groups, and in some benign teratomas was characteristically high. CONCLUSION: An intense lipid peak at 1.3 ppm is observed in malignant ovarian tumors but not in benign epithelial tumors. 1H- MRS may therefore be helpful in the differential diagnosis of adnexal lesions.

Lymphangioleiomyomatosis (LAM) is a rare idiopathic disease and this is characterized by a proliferation of abnormal smooth muscle cells in the lungs and in the lymphatic system of the thorax and retroperitoneum. The female genital tract is rarely affected by LAM. We report here on the CT and MR imaging findings of extensive LAM involving the uterus and pelvic cavity, and this was seen as multiple cystic uterine and parauterine masses with internal hemorrhage in a young female with tuberous sclerosis complex.

BACKGROUNDWith the advent of color Doppler flow imaging (CDFI) and technological development of detection of serum tumor markers, new opportunities are presented to the improved risk of malignancy index (RMI) based on Jacobs' research for predicting ovarian malignancy in patients with adnexal masses.

METHODSOne hundred and eighty women with an adnexal mass admitted for primary laparotomy were studied. Tumor specific growth factor (TSGF) adjusted ultrasound scores and the results of Doppler blood flow analysis were obtained before the operation. Based on the parameters which had been studied in Jacobs' research, TSGF levels and the findings of color Doppler flow imaging, the risk of malignancy model was redesigned using a binary Logistic regression model. The diagnostic efficacy of the improved risk of malignancy index (improved RMI) was compared with the Jacobs' model RMI by receiver operator characteristic (ROC) curve.

RESULTSThe ROC curve showed a higher sensitivity (Mcnamer's test, P < 0.05) in the discrimination between benign and malignant adnexal masses for the improved RMI than the RMI. Compared with the RMI, the improved RMI had an advantage in prediction of ovarian germ cell tumors and granular cell tumor (28.57% vs.71.43%, P < 0.05) and the early stage tumors and borderline tumors (33.33% vs. 66.67%, P < 0.05).

CONCLUSIONThe predictability of the improved RMI is better than the classic Jacobs' model, especially in diagnosis of the ovarian germ cell tumors and granular cell tumor and other early stage adnexal tumors.

OBJECTIVETo evaluate the diagnostic values of four risk of malignancy indices (RMI) for malignant adnexal masses.

METHODSThe data of 223 women with adnexal masses admitted to the Department of Obstetrics and Gynecology of Peking Union Medical College Hospital for surgical exploration between June 2008 and December 2008 were retrospectively analyzed. The sensitivity, specificity, positive predictive value and negative predictive value of RMI1, RMI2, RMI3, and RMI4 in the diagnosis of malignant adnexal masses were calculated.

RESULTSWhen the cutoff levels of RMI1, RMI2, RMI3 were set at 200 and RMI4 at 450, the sensitivities for diagnosing malignant adnexal masses ranged 59.0%-67.2%, the specificities ranged 94.4%-96.9 %, the positive predictive values ranged 82.0%-87.8%, and the negative predictive values ranged 90.9%-92.6%. The Youdens indexes (YI) of RMI1, RMI2, RMI3, and RMI4 were 0.559,0.606,0.576, and 0.559, respectively. RMI2 was significantly different from RMI1 (P=0.000), RMI3 (P=0.008), and RMI4 (P=0.000) in terms of diagnostic efficiency. RMI1, RMI2, RMI3, and RMI4 at a cutoff level of 75.688.679.1, 177.2 respectively, according to ROC curves, yielded sensitivities of 77.8%-82.5%, specificities of 84.6%-90.1%, positive predictive values of 69.0%-75.4%, and negative predictive values of 90.9%-92.6%; the relevant YI of RMI1, RMI2, RMI3, and RMI4 were 0.635, 0.665, 0.651 and 0.705, respectively. Under this cutoff level, the difference between RMI1, RMI2, RMI3, and RMI4 in diagnosing malignancy had no statistic significant. The primary histological types arising false negative were early stage epithelial ovarian cancer and non-epithelial ovarian cancer. The primary histological types arising false positive were endometriosis masses and degenerative sex cord-stromal tumor.

CONCLUSIONSRMIs are useful indices for the differentiation between benign and malignant pelvic diseases. Meanwhile, their cutoff levels for Chinese populations need further study.

OBJECTIVE: To evaluate the increased value of using coronal reformation of a transverse computed tomography (CT) scan for detecting adnexal torsion. MATERIALS AND METHODS: This study included 106 woman suspected of having adnexal torsion who underwent CT with coronal reformations and subsequent surgical exploration. Two readers independently recorded the CT findings, such as the thickening of a fallopian tube, twisting of the adnexal pedicle, eccentric smooth wall thickening of the torsed adnexal mass, eccentric septal thickening of the torsed adnexal mass, eccentric poor enhancement of the torsed adnexal mass, uterine deviation to the twisted side, ascites or infiltration of pelvic fat, and the overall impression of adnexal torsion with a transverse scan alone or combined with coronal reformation and a transverse scan. The areas under the receiver operating characteristic curves (AUCs), sensitivity, specificity, and positive predictive value were used to compare diagnostic performance. RESULTS: Fifty-two patients were confirmed to have adnexal torsion. The addition of coronal reformations to the transverse scan improved AUCs for readers 1 and 2 from 0.74 and 0.75 to 0.92 and 0.87, respectively, for detecting adnexal torsion (p < 0.001 and p = 0.004, respectively). Sensitivity of CT for detecting twisting of the adnexal pedicle increased significantly for readers 1 and 2 from 0.27 and 0.29 with a transverse scan alone to 0.79 and 0.77 with a combined coronal reformation and a transverse scan, respectively (p < 0.001 and p < 0.001, respectively). CONCLUSION: Use of a coronal reformation with transverse CT images improves detection of adnexal torsion.
