This diagnostic study evaluated the accuracy of transvaginal sonography for identifying endometrial cysts among 98 outpatients at a hospital in Jakarta, Indonesia. The researchers compared imaging results against histological findings from surgically removed masses, which served as the gold standard for confirmation. The analysis revealed that transvaginal sonography achieved an overall accuracy of 85 percent, with a sensitivity of 93 percent and specificity of 77 percent, significantly outperforming clinical examination alone. This paper is centrally about endometriosis — specifically the diagnostic utility of imaging for endometriomas, also referred to as endometrial cysts in the text.

Abstract

Endometriosis is common in women of reproductive age. Late diagnosis is still the main concern. Currently, noninvasive diagnostic testing, such as transvaginal sonography, is recommended. The aim of the current study was to evaluate the accuracy of transvaginal sonography in diagnosing endometrial cysts in patients in Cipto Mangunkusumo Hospital, Jakarta, Indonesia. This diagnostic study was carried out at Cipto Mangunkusumo Hospital between January 2014 and June 2015. Outpatients suspected have an endometrial cyst based on the patient history and a clinical examination was recruited. The patients were then evaluated using transvaginal sonography by an experienced sonologist, according to the research protocol. The gold standard test was a histological finding in the removed surgical mass. Ninety-eight patients were analyzed. An endometrial cyst was confirmed by histology in 85 patients (87%). The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of transvaginal sonography was established to be 85% (a range of 71-99%), 93%, 77%, 96%, and 63%, respectively. A significantly higher area under the curve was identified using transvaginal sonogpraphy compared to that achieved with a clinical examination alone (85% versus 79%). Transvaginal sonography was useful in diagnosing endometrial cysts in outpatients and is recommended in daily clinical practice.
