Massive amebic liver abscess--an unusual presentation

A 40-year-old woman presented with a huge lump in the right half of the abdomen and irregular menses. Ultrasonography showed a cystic lump with septations, extending from the upper abdomen to the pelvis; the right ovary was not seen. On exploration, there was a large cyst arising from the right lobe of the liver; the aspirate was bilious. Since the cyst wall was adherent to retroperitoneal structures, complete excision was not possible. A roux-en-Y loop of jejunum was anastomosed to the cyst wall. Biopsy of the wall showed inflammatory granulation tissue with trophozoites of Entamoeba histolytica. She was treated with metronidazole, and recovered uneventfully.
