Endometrioma of the liver.

Hepatic endometriosis is extremely rare. The diagnosis is often missed and treatment is delayed. A 37-year-old woman was referred to the gynaecology department with vague abdominal pains. She had a past history of pelvic endometriosis and hysterectomy with bilateral salpingo-oophorectomy. Further investigations in due course confirmed it to be endometriosis of the liver. She was eventually referred to the hepatobiliary unit, almost three years after her first presentation, where she was operated on with good results.
