ABSTRACT

Background: Adenomyosis of uterus is difficult to diagnose clinically because of nonspecific symptoms and signs. Accurate diagnosis can be achieved with imaging. Objective: To study imaging findings of adenomyosis of uterus by EVUS and MRI with histopathological correlation and to evaluate accuracy of EVUS and MRI in diagnosis of adenomyosis. Material & Methods: Prospective study of 50 patients in age group of 30-59 years, presenting clinically with menorrhagia, dysmenorrhea, pelvic discomfort, low backache and uterine enlargement underwent EVUS and MRI. Imaging findings were correlated with histopathology reports from biopsy and operated cases. Results: Adenomyosis of uterus was confirmed in 41 patients, 38 patients were diagnosed correctly on magnetic resonance imaging. MRI showed 2 false positive and 3 false negative diagnosis. EVUS correctly diagnosed 33 patients. It showed 4 false positives and 8 false negatives. Sensitivity of MRI was 92.68% and specificity was 81.82%. EVUS showed sensitivity of 80.49% (p<0.001) and specificity of 69.23% (p=0.41). Conclusion: EVUS and MRI are extremely accurate methods of diagnosing uterine adenomyosis. MRI is more precise than EVUS.
