Hello,Welcome to HCM, I am Dr. Das
Firstly increased endometrial thickness indicates endometrial hyperplasia
which may be simple or complexed. In other neoplastic conditions, it can also be seen.
Now, in left ovary there is space occupying lesions. It has calcification. That means may be there is aneoplastic changes. Which may be benign or neoplastic.
Consult with your treating doctor about clinical correlation.
