title: Life-threatening pica: liver abscess from perforating foreign body.
abstract: A case is presented of a patient with a psychiatric illness and pica who developed a pyogenic liver abscess due to perforation of the duodenum by a pen. This report emphasizes the importance of ultrasound and computed tomography in making a rapid diagnosis. The relative superiority of ultrasound was revealed because an anaesthetic was not required for scanning, and in addition to the liver abscess, the precise location of the perforating foreign body was demonstrated.
