Hello, Thank you for your query. This report indicates that the lining within the uterus (endometrium) is thicker than expected. *how old is your mother? *does she still get her period? If not, when did it stop? *how many children does she have? *any previous surgery? *does she have any other medical issues or take any medications? *does she have any bleeding or abdominal pain? *why was this scan done? *has she had any weight loss or fatigue? The reports suggests either a blood clot or an increased growth (abnormal) of the endometrium. I recommend : -an OBGYN consult -pap smear -blood tests (complete blood count) -repeat ultrasound after 3 months or sooner if there is any unusual vaginal bleeding. - a D&C (dilatation and curettage), if indicated after each months or sooner if there is bleeding The report suggests a repeat scan and a consult with her OBGYN. Please make sure you discuss all options with her doctor. The trend is to advise surgery as a prevention of cancer but that is not necessary unless there is evidence that it could be cancer or develop into one. Get a second or even a third opinion, if required. Sometimes during menopause and a for a few years after, endometrium can be thick. Examining this and keeping a close eye on it by regular follow up is important. Based on this report alone, a diagnosis cannot be made. So don t worry, just consult an OBGYN. Hope this helps. Please let me know if there is anything else I can help you with. Wish you good health
