Isolated rupture of an accessory liver from blunt abdominal trauma in childhood.

An accessory liver is uncommonly encountered in surgical practice. It can rarely cause acute abdominal pain. An isolated injury to an accessory liver from blunt trauma in a 10-year-old boy caused major intraperitoneal haemorrhage. Laparotomy and excision of the lacerated accessory liver lobe was necessary; the patient recovered uneventfully. The literature on accessory liver is reviewed.
