Abstract

A 78-year-old woman with a history of colon cancer with metastasis to the liver was presented to our emergency department because of bilateral groin pain and difficulty in walking, which had gradually increased during the previous 5 days. The pain was of sudden onset, radiating to the back, without aggravating or relieving factors. It was associated with constipation, dysuria and vaginal discharge. She reported passing fecal matter from the vagina one month ago. On physical examination, she appeared malnourished. Her blood pressure was 98/65 mmHg, with a 108 beats/min heart rate and 28 breaths/min respiratory rate. She was afebrile. Physical examinations were unremarkable, except for pale conjunctiva, abdominal distention, and diffuse tenderness especially over the umbilicus with guarding tenderness. Bowel sounds were decreased. Pelvic examination showed a yellowish odorous vaginal discharge from the external orifice of uterus. A complete blood cell count showed the following: leukocyte count, 34,200/mm3; segmented neutrophils, 87.5%; hemoglobin level of 7.4 mg/dl; hematocrit, 18.8%; and platelet, 180000/uL. Other laboratory studies included: glucose, 86 mg/dL; serum urea nitrogen, 28 mg/dL; serum creatinine, 0.87 mg/dL; sodium, 142 mEq/L; potassium, 4.8 mEq/L; albumin, 2.5g/dL; a carbohydrate antigen 19-9 level of 3,244 U/ml, and a carcinoembryonic antigen (CEA) level of 64.6 ng/ml. Coronal and axial cuts of patient’s abdominopelvic computed Tomography (CT) are shown in figures 1 and 2.
