CT Diagnosis of Ovarian Germ Cell Tumors / 实用放射学杂志

Objective To inquire into the CT feature of ovarian germ cell tumors.Methods 46 surgical and pathalogic proved ovarian germ cell tumors in 37 cases with their CT appearance were analyzed retrospectively.The characteristics of their images were discussed correlated with their pathology.Results 46 germ cell tumors in 37 cases composed of 43 teratoma,2 endodermal sinus tumor and 1 mixed germ cell tumor.For teratoma of the ovary,the sensivity of CT and US was all 100%,the specificity of CT and US was 93.02% and 58.14%.In the 30 patients with 38 benign cystic teratomas,CT demonstated 35 tumors in 27 patients,all had fat attenuation,5 had fat-fluid level,11 had a round mass in the cyst,16 had calcification or tooth.5 immature teratoma presented as mainly cystic or solid mass with some calcification and a little small pieces of fat attenuation.Some curved band-like low attenuation area in 1 solid mass were also found on CT.1 endodermal sinus tumor presented as cystic mass and the other one presented as mainly solid mass with large irregular hypodense necrotic area.Mixed germ cell tumer presented as solid mass with irregular border.Conclusion Ovarian teratoma and endodermal sinus tumor had their characteristic CT features.Particularly for teratoma,CT is a better image modelity with specific nature,compared with US.

X-ray Diagnosis of the Intraductal Papilloma of Breast / 实用放射学杂志

Objective To analyse the X-ray characteristics of the intraductal papilloma and to improve the diagnostic accuracy.Methods The mammographic data of 80 cases of intraductal papilloma of breast by pathology were analysed.Results 24 cases showed circular filling defect, 12 cases showed stringy filling defect,ductal blocked in 30 cases, ductal dilation in 48 cases. Conclusion Galactography is a effective method for diagnosing intraductal papilloma of the breast.

CT Findings and Staging of Ovarian Cystadenocarcinoma / 实用放射学杂志

Objective To investigate CT features and the staging of the ovarian cystadenocarinoma.Methods The CT findings of 73 ovarian cystadenocarcinomas proved by surgery and pathology in 52 cases were analyzed.CT staging in 41 cases with whole abdominal scan was made and the CT finding was compared with operative results.Results Of 73 ovarian cystadenocarcinomas,23(31.5%) tumors were typeⅠ(mainly cystic),32(43.8%)tumors were type Ⅱ(mixed) and 18(24.7%) tumors were type Ⅲ(mainly solid).The preoperative stage accuracy for stage Ⅲ patients was 90.9%.Conclusion CT manifestations of ovarian cystadenocarcinoma are varient,the definite diagnosis can be made by typical appearance.CT scan has a high accuracy in staging of preoperative.

Endodermal Sinus Tumor of the Ovary:Ultrasonography and CT Evaluation / 实用放射学杂志

Objective To explore the imaging(Ultrasonography and CT)characteristics of endodermal sinus tumor of the ovary.Methods US and CT images of endodermal sinus tumor of the ovary in ten patients were analyzed proved by operation and pathology retrospectively and the imaging characteristics were discussed correlated with their pathology.Results All ten patients underwent sonography.In addition,five patients underwent CT scans.On sonography,five showed solid echo,two showed cystic-solid echo and the other two showed cystic echo.The blood flow of solid parts were abundant.In local part,honeycomebed appearance could be seen.On CT,one presented as solid mass with large irregular hyperdense necrotic area,two presented as cystic-solid mass with irregular and blurred cystic area,the other two presented as predominantly cystic mass with multiple internal septations.Conclusion Endodermal sinus tumor of the ovary has their characteristic sonography and CT features,particularly for CT.These imaging characteristics with the patients' age and serum a-fetoprotein levels can be helpful in presurgical accurate diagnosis.

CT Diagnosis of Broad Ligament Leiomyoma / 实用放射学杂志

Objective To investigate the CT diagnostic value of broad ligament leiomyoma.Methods CT appearances of 21 cases with broad ligament leiomyoma confirmed by operation and pathology were analyzed retrospectively.Results CT showed that the tumors were pelvic and extrauterine masses in all cases,the tumors were solid in 19 cases and was cystic-solid in one case. The tumors had clear border in 16 cases and unclear border in 3 cases. The density of tumor in 6 cases were homogeneous, which was similar to that of myometrium on precontrast scanning. There was obviously uptake on postcontrast enhancement, as in myometrium. In heterogeneous tumors, low density areas of light flakes or streaks were observed, and the density of tumor solid part was somewhat lower than that of the uterus muscles on postcontrast enhancement. The tumors grew near the uterus. The shape of tumors appeared multitudinous, which was multilobular or irregular in 11 cases, flat round in 4 cases, and round or elliptic in 6 cases. Conclusion CT is a useful tool in diagnosis of the broad ligament leiomyoma.
