A 52-year-old woman was admitted to the hospital because of increased abdominal girth. About two months prior to admission she noted unexpected weight gain of 10 lbs. This was followed by ankle swelling when she stood up for long periods, and progressed to the point that her clothes became too tight. She said it felt like she was pregnant.
Over the course of the last two weeks she noted increased fatigue, more difficulty sleeping and dyspnea on exertion. Today she claimed that her abdomen and shoulders hurt so she sought medical attention. She has a history of alcohol abuse over the past 20 years, and was hospitalized once for pancreatitis related to alcohol, but had no history of liver disease. She denied any chest pain, cough, change in bowel habits, jaundice, vaginal or rectal bleeding. She lives with her husband and has three healthy children. She has no family history of similar problems; her parents both died of heart disease.
