Accessory liver lobe torsion presenting after blunt abdominal trauma

Torsion of an Accessory Liver Lobe (ALL) is a rare cause of acute abdominal pain. The presence of ALL is associated with congenital abdominal wall abnormalities, such as omphalocele or umbilical hernia, and occurs secondary to abnormal liver morphogenesis and intraabdominal hypertension causing liver hypertrophy. Torsion may be triggered by blunt abdominal trauma. We report the case of a 29-year-old male who developed torsion of an ALL arising from hepatic segment 3 after falling. The patient required urgent operative intervention for the treatment of this torsion. This presentation and disease manifestation has been very rarely reported in the literature.
