Abstract
Introduction: A huge, pedunculated, multiseptated, cystic pelvic mass with normal uterus may cause misinterpretation of the computed tomography (CT) scan, magnetic resonance imaging (MRI) scan and PET-CT as a malignant ovarian epithelial tumor.
Case Report: A 56-year-old multipara woman complained of lower abdominal pain, abdominal distension and she consulted to local hospital. Cancer antigen 125 (CA-125) was 59.6 U/mL and the CT, MRI and PET-CT revealed that a large multiseptated cystic mass (20 cm) with soft tissue parts, multiple hemorrhage and fluid-fluid levels and that the uterus was normal finding with some ascites. Those images suggested that it might be a malignant ovarian epithelial tumor with hemorrhage. We performed an exploratory laparotomy with suspicion of ovarian malignancy and found out that the pedunculated mass was originated from the uterine fundus and that the ovaries were normal. There was a small amount of serous ascites.
Conclusion: In this study, it is suggested that clinicians carrying out differential diagnosis of pelvic mass with increasing serum CA-125 level and ascites should consider not only ovarian cancer but also myoma with cystic degeneration.
