AIM To evaluate the performance of subjective evaluation of ultrasound findings (pattern recognition) to discriminate endometriomas from other types of adnexal masses and to compare the demographic and ultrasound characteristics of the true positive cases with those cases that were presumed to be an endometrioma but proved to have a different -histology (false positive cases) and the endometrio...

Two distinct spore appendage types of Clostridium bifermentans, a pinlike appendage and a tubular appendage, were studied by electron microscopy. The pinlike appendage is characterized by a shaft, about 100 A in diameter, which has a lobed caplike structure. The tubular appendage, 500 to 600 A in diameter, is characterized by a hirsute region consisting of small filaments or fibrils. Gross morp...

BACKGROUND Ovarian cancer is one of the highest mortality cancers in gynaecology. Discrimination of benign masses from malignant ones may sometimes become a challenge for the clinician since there is not a reliable tumour marker, thus some unnecessary, highly morbid operations can be performed. AIMS To explore the efficacy of human epididymis 4 (HE 4) and cancer antigen 125 (CA 125) markers i...

OBJECTIVES To determine the effect of an ultrasound training course on the performance of pattern recognition when used by less experienced examiners and to compare the performance of pattern recognition, a logistic regression model and a scoring system to estimate the risk of malignancy between examiners with different levels of experience. METHODS Using ultrasound images of selected adnexal...

Aims and Objectives: The aim of this diagnostic observational study was to find an association of final diagnosis of adnexal masses suggested by MRI and compared it as an imaging modality in determining the origin, nature (benign/malignant) & characteristics of adnexal masses by calculating sensitivity, specificity, and diagnostic accuracy. Materials and Methods: The present study was carried o...

Until recently, surgical treatment of a benign adnexal mass implied a laparotomy. In recent years, the development of laparoscopic surgery, as well as ultrasound-guided aspiration techniques, have significantly modified the treatment options for these patients. These procedures have shown considerable advantages. They have reduced surgical trauma and have shortened the hospital stay. We present...

Magnetic resonance imaging (MRI) increases the specificity of imaging evaluation for adnexal masses, especially when they are indeterminate on ultrasound, very large or when further imaging is required to establish tissue characteristics. This article is a pictorial essay describing the value of MRI in characterizing adnexal masses.

a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...

Due to widespread use of pelvic and transvaginal ultrasound in routine gynecological evaluation, the incidental finding of adnexal masses has led to discussions about management in asymptomatic patients regarding the risk of ovarian cancer. Transvaginal ultrasonography remains the modality of choice in the evaluation of suspicious characteristics. The combined analysis of ultrasound morphologic...
