Evaluating Adenomyosis with Transvaginal Sonography: Diagnostic Precision and Clinical Relevance

Abstract

Background: Adenomyosis is an important benign gynecological condition among females with variable signs and symptoms. Prompt detection of suspicious cases is important for the effective management of the disease. The objective of the current study was to determine the frequency of adenomyosis on transvaginal ultrasound (TVS), its diagnostic accuracy, and the identification of associated factors in women with symptoms of adenomyosis. Methods: This cross-sectional study was carried out at the radiology department of Dow University Hospital, Karachi, Pakistan from January 2022 to March 2023. All married females of reproductive age group presented with symptoms of adenomyosis for more than 7 days were included. Adenomyosis on TVS and histopathology were noted. Moreover, associated factors of adenomyosis were also studied. Results: Of 280 patients, adenomyosis on TVS was observed in 180 (64.3%) patients whereas on histopathology in 176 (62.9%) patients. Diagnostic accuracy of adenomyosis on TVS showed that sensitivity was 89.20%, specificity 77.88%, positive predicted value 87.22%, negative predicted value 81.00%, and accuracy was found to be 85.00%. A significantly higher proportion of adenomyosis was observed among women who had infertility (p<0.001), symptoms of dysmenorrhea (p <0.001), dyspareunia (p<0.002), urinary symptoms (p <0.001), and GI symptoms (p<0.001). Conclusion: TVS is a valuable imaging modality for identifying adenomyosis, especially in patients with clinical symptoms. Furthermore, there is a significant association between adenomyosis and various clinical symptoms, including infertility, dysmenorrhea, dyspareunia, urinary symptoms, and gastrointestinal symptoms.
