title: [Spontaneous pre-vesical haematoma in a patient under anticoagulant treatment].
abstract: OBJECTIVE
  To report a case of perivesical hematoma without previous trauma in a patient under anticoagulant treatment.
  
  
  METHODS
  A 70-year-old female admitted with a transitory ischemic cerebrovascular accident was given sodium heparin. Four days later she presented with abdominal distention and hypogastric discomfort. Abdominal ultrasound showed a big perivesical hematoma.
  
  
  RESULTS
  CT scan confirmed the presence of a big hematoma. The hematoma was drained five days later after an optimal coagulation profile. Patient was discharged with normal ultrasound after an uneventful postoperative course.
  
  
  CONCLUSIONS
  Spontaneous bleeding in patients with coagulation abnormalities is a well-known event, although there are few bibliographic references about primary perivesical blood collections. We opted for deferred drainage of the hematoma to avoid perivesical fibrosis.
