In an 18-year-old woman with abdominal complaints of unknown origin, ultrasonography and CT showed a large abnormal structure in the left half of the liver. Biopsy showed this to be an abscess. Because Staphylococcus aureus was cultured and the patient had suffered from a navel infection after navel piercing several months earlier, it was concluded that the infection had spread through the ligamentum teres hepatis to cause the liver abscess. The abscess was drained and the patient was treated successfully with antibiotics.
