Final Diagnosis Cornual Pregnancy
Discussion On endovaginal scanning, the endometrial cavity appeared normal with endometrial thickness of 10mm. There is a thick walled cystic structure with a small floating lightly echogenic mass inside.  The mass is seen in right of the fundus separate from the endometrial cavity. It appeared either a intramural fibroid with cystic degeneration or a cornual pregnancy with a dead embryo inside it. The positive gravindex test of the urine clinched the diagnosis in favour of the later.  
Follow Up The patient opted for hysterectomy instead of removal of the mass. Our diagnosis was proved at the laparotomy.
