Hello, thanks for posting your query on HCM. The uterus cervix and ovaries are normal in size and appearance. Cul-de-sac, which is a space behind the uterus also shows no abnormality like fluid collection. The finding that stands out is a thickened endometrium i.e. the internal lining of uterine cavity. A variety of causes such as benign hyperplasia, polyps, and malignancy are in the differential. However, a correlation with your age, whether you are menstruating, on any medication and current symptoms are important to make a diagnosis. Kindly speak to your gynecologist. You might be asked to go for a test to sample a bit of the endometrium. Hope this is helpful. Please write in again if you have any more queries. All the best.
