The purpose of this study was to correlate the sonographic and histologic
findings of focal lesions of the endometrium as depicted by transvaginal
sonography. Sixteen focal endometrial masses were encountered during an 8
month period. The transvaginal sonographic appearance was correlated with
findings at surgery or hysteroscopy. All uniformly hyperechoic endometrial
masses were benign endometrial polyps. Five heterogeneous lesions were
complicated endometrial polyps; one of these showed a focus of endometrial
carcinoma. Four small and uniformly hypoechoic lesions were all prolapsed
submucosal leiomyomata. Our results showed that a well-defined, uniformly
hyperechoic mass within the endometrial cavity is most suggestive of a
benign endometrial polyp. Larger masses with a heterogeneous appearance are
nonspecific and warrant further evaluation and biopsy.
