Synchronous bleeding of liver adenomatosis and possible relation to acoustic trauma.

BACKGROUND: Solitary hepatic adenoma is a rare tumour but adenomatosis of the liver is even less common; it has been defined arbitrarily as more than four adenomas within otherwise normal hepatic parenchyma. Usually asymptomatic, the main clinical presentation is abdominal pain secondary to bleeding from the tumour. CASE OUTLINE: A 40-year-old woman admitted for abdominal pain and operated within a few hours due to circulatory instability was found to have synchronous bleeding from three out of four liver cell adenomas. The onset of pain followed shortly after exposure to particularly loud music. The three bleeding tumours were enucleated. The fourth lesion was left in situ; during outpatient follow-up it decreased in size and eventually disappeared. DISCUSSION: Although rupture with bleeding is a well-known presentation of liver cell adenomas, synchronous bleeding from more than one tumour is exceedingly uncommon and this may be the first reported case. Enucleation of the tumour is easy to perform even during active bleeding. Small asymptomatic tumours may be followed without surgical intervention.
