(A) Abdominal computed tomography: demonstrated a solid right adnexal region mass (white arrow), and a cystic mass originated from the left adnexal region (black arrow). (B and C) Pelvic ultrasound: demonstrated a cystic mass (black arrows) in the left adnexal region. It was unilocular and homogenous, with low-level internal echoes, a well-defined wall, and no solid areas or internal blood flow. In the right adnexal region, a mass with a solid appearance and similar echogenicity to the myometrium (white arrow) was identified.
