The potential role of elastography in differentiating between endometrial polyps and submucosal fibroids: a preliminary study

Endometrial polyps and submucosal fibroids are common causes of abnormal uterine bleeding (AUB) and less commonly infertility The prevalence of such intrauterine lesions increases with age during the reproductive years, and usually decreases after menopause The first-line imaging examination in the diagnosis of endometrial polyps as well as submucosal fibroidsis ultrasound, but its accuracy is not obvious Elastography is an ultrasound-based imaging modality that is used to assess the stiffness of examined tissues Considering the fact that endometrial polyps derive from soft endometrial tissue and submucosal fibroids are made of hard muscle tissue, elastography seems a perfect tool to differentiate between such lesions I present two groups of patients with AUB and intrauterine lesions suspected on ultrasound In the first group of patients, elastography showed that the stiffness of the lesion was similar to the endometrium and softer than the myometrium During hysteroscopies endometrial polyps were removed In the second group of patients, elastography showed that the stiffness of the lesion was similar to the myometrium and harder than the endometrium During hysteroscopies submucosal fibroids were removed In both groups, the diagnosis was confirmed by the pathological examination in all cases It was demonstrated that with the use of elastography it is possible to assess the stiffness of intrauterine lesions, which may be useful in differentiating between endometrial polyps and submucosal fibroids
