The diagnostic value of transvaginal ultrasonography tosubmucous myoma and endometrial polypsYan P, The Second Hospital Of The Third Military MedicalUniversity, China

Objectives: To evaluate the value on transvaginal B-ultrasonic diag-nosis of submucous myoma and endometrial polypsMethods: The image of 96 cases submucous myoma and endometrialpolyps demonstrated by operation and pathology was retrospectivelyanalyzed to investigate the diagnosis accordanceResults: Eighty-three of the total 96 cases were demonstrated byoperation and pathology to accord with the diagnosis of transvaginalultrasonography. Twenty-nine cases of submucous myoma were accu-rately diagnosed and the diagnosis accordance was 90.6%, and 55 casesendometrial polyps were correctly diagnosed with 84.37% diagnosisaccordance.Conclusions: Transvaginal ultrasonography has practical usage in thediagnosis and differential diagnosis in submucous myoma and endo-metrial polyps.

The diagnostic accuracy of transvaginal sonography in uterinepathologyHong SC, Kim YJ, Yoo SW, Park EA, Kim T, Lee KW, Kim SH,Korea University Medical Center, Korea

Objectives: The purpose of this study is to evaluate the diagnosticaccuracy in uterine pathology between transvaginal ultrasound andhysteroscopy.Methods: During the period from January 1995 to May 2005, 277women underwent hysteroscopy combined with transvaginal ultra-sound due to evaluate the cause of infertility and endometrial pathologyat Department of Obstetrics and Gynecology in Korea UniversityHospital.Results: Mean age of the study group was 37.3 and mean parity was1.13. According to pathologic reports, final diagnosis were normalfinding (43.5%), polyp (20.8%), submucosal myoma (11.1%), endo-metritis (9.7%), endometrial hyperplasia (2.8%) and endometrial can-cer (1.4%) etc. The transvaginal ultrasound showed 57.89% sensitivity,65.26% specificity and 75.0% positive predictive value in detectingendometrial lesions. The sensitivity, specificity and positive predictivevalue of hysteroscopy were 92.61%, 69.66% and 85.5%, respectively.Overall agreement of transvaginal ultrasound and hysteroscopic findingwas 58.7%. Hysteroscopy showed much higher detection rate in case ofsynechiae and endometritis compared with transvaginal ultrasound.Conclusions: Hysteroscopy was significantly better diagnostic proce-dure than transvaginal ultrasound. But transvaginal ultrasound alsohelpful in diagnosis of polyp, submucosal myoma and in evaluation ofmyometrium and adnexa. So, we concluded that both hysteroscopy andtransvaginal ultrasound are useful methods in detection of endometriallesion.

The application value in diagnosis of ectopic pregnancy usingtransvaginal ultrasonographyWang YH, 1st People’s Hospital ShuangLiu, ChengDu, SiChuan,China

Objectives: To study the application value in diagnosis of ectopicpregnancy using transvaginal ultrasonography (TVS).Methods: To review analyzes 45 the cases of ectopic pregnancy fromthe 2003 November to 2005 September in our hospital through com-

bined transabdominal ultrasonography (TAS) and TVS checkingthrough surgical operation and pathology confirming.Results: Thirty-seven cases were diagnosed with TAS (82%, 37/45)and 43 cases with TVS (95.5%, 43/45) in 45 cases.Conclusions: TVS is better than TAS in diagnosis of ectopic preg-nancy. It is a feasible, reliable imaging modality.

The value of ultrasonography in the diagnosis of ovarian surfaceserous papillary cystadenocarcinomaLiu H, Wu X, Liu S, Wang N, Liu M, Fourth Teaching Hospital ofHebei Medical University, China

Objectives: To explore the clinical value of 2D-TAS and 2D-TVS inthe diagnosis of ovarian surface serous papillary cystadenocarcinomaMethods: To find the specific ultrasound features, the color Dopplerflow image and the clinicopathological characteristics were analyzedretrospectively.Results: The ultrasound features of ovarian surface serous papillarycystadenocarcinoma could be divided into three types.Conclusions: Applying three types of the ultrasound features mayenhance the diagnostic accurate rate for ovarian surface serous papil-lary cystadenocarcinoma.

Pregnancy-associated ovarian diseaseMoon MH, Lee YH, Cho JY, Cho HC, Lee MS, Lee EJ, Kim KA,Samsung Cheil Hospital, Sungkyunkwan University School ofMedicine, Korea; Ajou University Medical Center, Korea; KoreaUniversity School of Medicine, Korea

The ovarian mass, encountered frequently on antenatal ultrasound, maygive clinicians some perplexing problems in the management of preg-nant women. This problem, occasionally, can be helped by ultrasound,which is the most commonly used imaging tool in pregnant women.This exhibition will present the broad spectrum of ultrasound imagingfindings of pregnancy-associated ovarian masses, arranged with sepa-rate subject sections, covering functional cysts, luteoma, acute pelvicpain, ovarian tumor and ovarian vein thrombosis. Hyperreactio lutei-nalis, ovarian hyperstimulation syndrome and polycystic ovarian dis-ease will be included in the functional cyst section.

Steatotic hepatocellular carcinomatosis mimicking malignantovarian teratomaTsai C-C, Liu Y-S, Huang S-C, Ko S-F, Chang Gung MemorialHospital, Taiwan; Veterans General Hospital, Kaohsiung, Taiwan;Department of Pathology Chang Gung Memorial Hospital,Kaohsiung, Taiwan;Department of Radiology, Chang GungMemorial Hospital, Taiwan

Hepatocellular carcinoma metastasizes to the ovary is extremely rare.Transvaginal sonography is a typically employed for differential diag-nosis of hyperechoic adnexal tumors in the pelvis. A 73-year old femalepresented with progressive abdominal fullness for 2 months prior toadmission. Transvaginal sonography identified ascites and a hypere-choic mass. Computed tomography (CT) demonstrated heteroge-neously enhanced nodules containing fat diffusely distributed through-out the peritoneal cavity. Abdominal sonography also revealed multiplehyperechoic peritoneal nodules without a primary hepatobiliary mass.Final diagnosis was disseminated peritoneal steatotic HCC with ovar-ian metastasis. This report highlights the fact that metastatic HCCshould be considered despite its rarity during differential diagnosis
