I had a spiral CT scan done for kidney stones. My doctor called and said that I need to take the films to my OB/GYN. I have a copy of the report and it reads "The uterus shows a high density mass in the region of the fundus projecting into the endometrial canal. This measures up to 2.5 cm in size. It is unclear if this represents a fibroid protuding into the endometrium or a mass arising primarily in the endometrium." What exactly does this mean? Should I be worried?
