Answer

See the list below:

  • In a review of 12 cases, Shen et al found that CT and MRI appearance of these tumors may be helpful diagnostic features. [8]
  • Triple-contrast CT scan of the abdomen and pelvis should be performed to evaluate the extent of disease and the involvement of lymph nodes and other adjacent structures (eg, bowel). Typically, struma ovarii appear as a multicystic mass with no or moderate cystic wall enhancement. [9]
  • Pelvic sonography is optional if a CT scan has already been performed. [10] Frequently, this is an initial study.
  • Mammography should be performed in patients with pelvic masses of unknown origin.
  • Chest radiographs should be obtained in patients with systemic symptoms or signs of disease spread in abdomen/pelvis to assess for lung metastasis.
  • In select cases, preoperative evaluation with uptake of sodium iodide I-123 has been performed to demonstrate thyroid uptake in pelvic masses.
