[Torsion and infarction of an accessory liver lobe]

Anatomical abnormalities of the liver are extremely rare. We report a case of a 32 year old female who has admitted with acute epigastric pain and vomiting. Physical exam revealed a mobile mass in right middle abdominal quadrant. Ultrasound and contrast--enhanced CT demonstrated a heterogeneous vascular left mass. Small bowel enema shows left jejunal loops displacement. Surgical findings: twisted, congested swelling, attached by a long pedicle to the liver's third segment. Histological examination showed recent hepatic infarction.
