The adhesion of the pelvic mass to the rectum and bladder in CT images and gross pathology (case 2). (a-b) The large ovarian mass closed the entrance to the pelvis. The lesion was a mixed type of cyst, which was closely connected with the iliac vessels and lateral wall of the pelvic cavity. (c) There was no distinct boundary between the mass and the uterus located in the rear. (a, d) The coronal and sagittal CR image showed that the ovarian mass violated the posterior wall of the bladder and the anterior rectal wall. The normal muscle wall structure of the above cavity viscera disappeared completely. (b, e) In the MPR image, the boundary of the lesion was displayed because of the ascites and urinary bladder, but the depth of the organ invasion was still difficult to determine. (f) VR showed poor effect and could hardly distinguish the lesion from its adjacent organs
