title: Bleeding into a liver cyst can be treated conservatively.
abstract: OBJECTIVE
  To report the case of a patient with haemorrhage in a large hepatic cyst.
  
  
  METHODS
  A 66-year-old man, who presented with right shoulder pain and subsequent sudden abdominal pain. A large hepatic cyst containing blood was found at ultrasonography.
  
  
  METHODS
  The patient was treated conservatively.
  
  
  RESULTS
  The patient's symptoms resolved quickly. No symptoms or complications recurred during a follow-up of 2 years.
  
  
  CONCLUSIONS
  Therapy for non-parasitic liver cysts is indicated when symptoms or complications related to the cysts occur. This case shows that spontaneous haemorrhage into a non-parasitic hepatic cyst may follow a benign course and may be treated conservatively.
