Massive ascites, pelvic mass, elevated CA-125 and weight loss: think outside the 'ovaries'.

A 44-year-old woman presented with 3 months' history of painless progressive abdominal distension and weight loss of more than 15 kg. Clinically a pelviabdominal mass with ascites was detected. CT scan of the pelvis and abdomen showed a subserosal leiomyoma with huge amount of ascites. Cancer Antigen (CA)-125 was 546 kU/L. Exploratory laparotomy with myomectomy was done and this was followed by dramatic improvement postoperatively.
