I Had Complete Hysterectomy (uterus And Overuse And Tubes) In

I had complete hysterectomy (uterus and overuse and tubes) in 2005. I just had pelvic and abdominal ultrasound 2 weeks ago. During the scan the technician asked if I was sure they took both overuse an I confirmed yes. Then my Dr. got the rad report which reported normal size right overie. I told Dr.I questioned that an so she got surf report confirmed both were removed. New rad report after second review states pelvic mass and rec MRI. I am now waiting insurance approval for the test. Any guesses what the mass could be? Uterus path came back adenomyosis.
