This 64-year-old female has stage II endometrial carcinoma, which had been resected before and treated with chemotherapy and radiation.  At the present time, the patient is under radiation treatment.  Two weeks ago or so, she developed a large abdominal mass, which was cystic in nature and the radiologist inserted a pigtail catheter in the emergency room.  We proceeded to admit the patient and drained a significant amount of clear fluid in the subsequent days.  The cytology of the fluid was negative and the culture was also negative.  Eventually, the patient was sent home with the pigtail shut off and the patient a week later underwent a repeat CAT scan of the abdomen and pelvis.
