Purpose: To evaluate the characteristic sonographic findings of ruptured endometrioma in comparison with unruptured endometrioma.
Materials and Methods: Fifty nine cases of pathologically proven endometrioma were categorized as the ruptured endometrioma group and the unruptured endometrioma group on the basis of the operation records. The sonographic findings such as locularity, the internal echotexture, the size and the wall thickness of the cyst and the presence of a fluid-fluid level, fibrin strands, a retracting clot and fluid in the pelvic cavity were retrospectively evaluated using logistic regression analysis.
Results: On univariate analysis, the sonographic finding of a thin wall (odds ratio, 4.1; 95% confidence interval: 1.2-13.8) and a fluid-fluid level (odds ratio, 9.0; 95% confidence interval: 2.4-33.6) were significantly different between the ruptured endometrioma group and the unruptured endometrioma group. Logistic regression analysis showed that a thin wall (odds ratio, 7.5; 95% confidence interval: 1.6-34.4) and a fluid-fluid level (odds ratio, 14.7; 95% confidence interval: 3.1-70.2) were both independent variables significantly associated with unruptured endometrioma.
Conclusion: The characteristic sonographic findings of ruptured endometrioma are a thin cystic wall and a fluid-fluid level in the cyst, as compared with those of unruptured endometrioma.
