The symptoms of struma ovarii are similar to those of other ovarian tumors and are nonspecific in nature. They can include the following:

·         Abdominal pain

·         Palpable abdominal mass

·         Abnormal vaginal bleeding

·         Ascites (reported in up to one third of cases) [2]

·         Pseudo-Meigs syndrome (ascites in the setting of hydrothorax) (reported in fewer than 10 cases)

·         Incidental discovery on pelvic imaging or surgery

Thyroid hyperfunction is a presenting symptom in 5-8% of patients with struma ovarii. [3]




Physical Examination

Struma ovarii is difficult to diagnose and physical examination often does not reveal any abnormalities. The tumor may present as a large abdominal mass, which can be palpable on examination depending upon size and location. Patients may also experience expanding abdominal growth and a fluid wave consistent with ascites. Rarely, dyspnea and pulmonary crackles can be indicative of Pseudo-Meigs syndrome.
