The classical example is an avascular unilocular cyst containing low-level, homogeneous "ground-glass" like internal echoes, as a result of the hemorrhagic debris. This appearance occurs in 50% of cases 7.

2023年2月24日 · Ultrasound. While the sonographic appearance of the uterus and endometrium may be normal in early stages, findings may include: thickened and heterogeneous endometrium; intracavitary/cul-de-sac fluid; increased vascularity on Doppler ultrasound; intrauterine air; loss of a well defined interface between the endometrium and myometrium

2023年7月20日 · Ultrasound features that are suggestive of endometrial carcinoma rather than hyperplasia include 17: heterogeneous and irregular endometrial thickening. polypoid mass lesion. intrauterine fluid collection. frank myometrial invasion.
