title: Torsed pedunculated hepatic hamartoma.
abstract: We report a 9-year-old boy with a 6-h history of acute abdominal pain due to torsion of a pedunculated hepatic mesenchymal hamartoma. The lesion was seen, on US and CT, to connect to the liver through a pedicle. Mesenchymal hepatic hamartomas are unusual tumours that may be pedunculated, and this is a unique case complicated by torsion. The radiological and pathological findings, differential diagnosis, and clinical course are discussed.
