Imaging in gynecological disease. 10: Clinical and ultrasound characteristics of decidualized endometriomas surgically removed during pregnancy.

OBJECTIVES: To describe the clinical history and ultrasound findings in women with decidualized endometriomas surgically removed during pregnancy. METHODS: In this retrospective study, women with a histological diagnosis of decidualized endometrioma during pregnancy who had undergone preoperative ultrasound examination were identified from the databases of seven ultrasound centers. The ultrasound appearance of the tumors was described on the basis of ultrasound images, ultrasound reports and research protocols (when applicable) by one author from each center using the terms and definitions of the International Ovarian Tumor Analysis (IOTA) group. In addition, two authors reviewed together available digital ultrasound images and used pattern recognition to describe the typical ultrasound appearance of decidualized endometriomas. RESULTS: Eighteen eligible women were identified. Median age was 34 (range, 20-43) years. Median gestational age at surgical removal of the decidualized endometrioma was 18 (range, 11-41) weeks. Seventeen women (94%) were asymptomatic and one presented with pelvic pain. In three of the 18 women an ultrasound diagnosis of endometrioma had been made before pregnancy. The original ultrasound examiner was uncertain whether the mass was benign or malignant in 10 (56%) women and suggested a diagnosis of benignity in nine (50%) women, borderline in eight women (44%), and invasive malignancy in one (6%) woman. Seventeen decidualized endometriomas contained a papillary projection, and in 16 of these at least one of the papillary projections was vascularized at power or color Doppler examination. The number of cyst locules varied between one (n = 11) and four. No woman had ascites. When using pattern recognition, most decidualized endometriomas (14/17, 82%) were described as manifesting vascularized rounded papillary projections with a smooth contour in an ovarian cyst with one or a few cyst locules and ground-glass or low-level echogenicity of the cyst fluid. CONCLUSIONS: Rounded vascularized papillary projections with smooth contours within an ovarian cyst with cyst contents of ground-glass or low-level echogenicity are typical of surgically removed decidualized endometriomas in pregnant women, most of whom are asymptomatic.

Misdiagnosed ectopic pregnancy mimicking adnexal malignancy: a report of two cases.

We present two cases of nulliparous women with no history of amenorrhea who were referred to our unit following finding of a hypervascularized solid adnexal mass. In both cases a malignant tumor of tubal origin was suspected at transvaginal sonography. However, following laparoscopy, histological examination revealed that the masses were the result of an undetected tubal ectopic pregnancy that had failed spontaneously, with massive vasodilatation of pelvic blood vessels surrounding the trophoblastic tissue. We recommend consideration of the potential diagnosis of a previously undetected, failed tubal ectopic pregnancy in fertile women presenting with an adnexal mass, even when there is no history of amenorrhea or a positive pregnancy test.

Multivariate analysis of the variables affecting left ventricular filling in normal subjects.

Pulsed Doppler measurements of left ventricular filling (LVF), two-dimensional and M-mode echocardiograms were performed in 189 healthy subjects, in order to evaluate factors influencing LVF Doppler indexes in normal subjects. LVF Doppler indexes (peak E, peak A, peak E/peak A, deceleration rate of peak E (ED) were related by univariate and multivariate analyses with the following parameters: age, sex, heart rate, systolic and diastolic blood pressure, aortic root and left atrial dimensions, left ventricular mass index, left ventricular shortening fraction. The stepwise analysis showed that age by itself explained up to 18% of peak E variance, 50% of peak A variance, 61% of peak E/peak A variance and 25% of ED variance. The other variables entered into the regression, slightly improved the predictive power (less than 10%). In conclusion, age is the major independent factor affecting LVF in normal subjects, although other variables show significant correlation also after age adjustment.
