Echogenic Mass (echogenic + mass)
Selected AbstractsAortic Tumor or Mobile Thrombus?ECHOCARDIOGRAPHY, Issue 2 2010Andrea Loiselle M.D., M.P.H. Isolated large mobile mass in the thoracic aorta can be due to thrombus or, rarely, aortic tumor. We report the case of a 61-year-old man with no history of medical problems presenting with neurologic deficits and in whom a large mobile echogenic mass in the distal aortic arch was found with transesophageal echocardiography. Given his few cardiovascular risk factors and absence of other systemic symptoms, he received anticoagulant therapy. Subsequent resolution of the aortic mass suggested a diagnosis of thrombus. This case illustrates an unusual manifestation of aortic arch atherosclerosis and underscores the utility of transesophogeal echocardiography for patients with ischemic stroke. (Echocardiography 2010;27:E21-E22) [source] Lipoma of the right atriumJOURNAL OF CLINICAL ULTRASOUND, Issue 3 2009Oyku Gulmez MD Abstract A 66-year-old asymptomatic woman was admitted to our hospital with the diagnosis of a right atrial mass detected on an outside transthoracic echocardiogram and confirmed on transesophageal echocardiography. Physical examination and basal electrocardiogram were normal. Transthoracic echocardiography revealed a 3.8 × 2.5 cm echogenic mass in the right atrium. A multislice CT examination demonstrated a right atrial mass with a fat density ranging from ,80 to ,110 HU. The patient had a successful surgical excision of the mass, and the diagnosis of lipoma was confirmed on histopathological examination. © 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2009 [source] Sonographic appearance of the uterine cavity following administration of mifepristone and misoprostol for termination of pregnancyJOURNAL OF CLINICAL ULTRASOUND, Issue 6 2006Ofer Markovitch MD Abstract Purpose. To describe the sonographic appearance of the uterine cavity in women after administration of mifepristone and misoprostol for termination of pregnancy. Methods. Thirty-six women treated with mifepristone 600 mg followed by misoprostol 400 ,g 2 days later for termination of pregnancy were the subjects of the study. Gestational age as calculated from the last menstrual period was ,49 days. Pretreatment sonographic parameters, including gestational sac size and crown,rump length, were measured. The sonographic appearance of the uterine cavity was recorded and documented 6 hours (T-1) and 14 days (T-2) after administration of misoprostol. Results. The mean menstrual age of the patients was 42 days (range 31,49 days). The mean gestational age according to crown,rump length was 43 days (range 40,48 days). Sonographic examination performed atT-1 revealed 23 patients (62.9%) with a well-defined echogenic mass located in the uterine cavity, 2 patients (5.5%) with an intrauterine sac containing a nonviable embryo, and 11 patients (30.5%) with an endometrium thickness of 7,14 mm with no evidence of intrauterine contents. Doppler flow signals were detected in 15 of the 23 patients (65.2%) with an echogenic intrauterine mass. Sonographic examination performed at T-2 revealed 19 patients (52.8%) with a persistent echogenic intrauterine mass; Doppler flow could be detected in 15 of these patients (78.9%). Dilatation and curettage was required in 2 patients (5.6%) due to failure of treatment; all others regained normal menses. Conclusions. An intrauterine echogenic mass with well-defined borders, with or without Doppler flow signals, can be detected 2 weeks after administration of mifepristone and misoprostol for termination of pregnancy. Because most of the women in our study regained normal menses without further surgical intervention, this finding could indicate remnants of trophoblastic tissue evacuated spontaneously from the uterine cavity. Therefore, dilatation and curettage should be avoided in these cases, unless clinical symptoms or signs necessitate surgical intervention. © 2006 Wiley Periodicals, Inc.

Parthenakis M.D. Abstract Background: The presence of atherosclerotic lesions in the thoracic aorta by transesophageal echocardiography (TEE) appears to be a marker for the presence of significant coronary artery disease (CAD) in the general population. Hypothesis: We investigated whether atherosclerotic lesions in the thoracic aorta, by multiplane TEE, could be a marker for CAD in elderly patients. Methods: In all, 127 patients (67 men, 60 women, aged 68 ± 13 years), underwent a TEE study with imaging of the thoracic aorta and cardiac catheterization with coronary angiography. The presence of a distinct, linear, or focal, highly echogenic mass protruding into the vessel lumen was the criterion for the diagnosis of atherosclerotic plaque. Results: Atherosclerotic lesions were found in 30 of 36 patients (83.3%) with and in 20 of 91 (22%) without CAD. Of the 41 patients , 70 years, atherosclerotic lesions were detected in 14 of 17 (82.3%) with and in 13 of 24 patients (54%) without CAD. The sensitivity, specificity, and positive and negative predictive values in this group were 82.3, 46, 52, and 78.6%, respectively. Multivariate logistic regression analysis revealed that in patients aged , 70 years only advanced atherosclerotic lesions were independent predictors of significant CAD. However, the high negative predictive value of the method indicates that the absence of aortic plaque is a strong predictor of the absence of CAD. Conclusions: The presence of atherosclerotic lesions in the thoracic aorta is a strong predictor of CAD only in patients < 70 years old. However, the negative predictive value of the method is high for all patients regardless of age. [source] | ||||||||||
