title: Cullen's sign following ultrasound-guided transvaginal oocyte retrieval.
abstract: OBJECTIVE
  To describe two cases of periumbilical hematoma (Cullen's sign) following ultrasound-guided transvaginal oocyte retrieval.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University-affiliated teaching hospital.
  
  
  METHODS
  Two patients, 34 and 32 years old, who developed Cullen's sign following ultrasound-guided transvaginal oocyte retrieval.
  
  
  METHODS
  Workup for pancreatitis and coagulopathies. Laparoscopy was preformed in one patient.
  
  
  METHODS
  Resolution of the symptoms.
  
  
  RESULTS
  Pancreatitis, coagulopathy, and massive hemoperitoneum were ruled out. Symptoms resided within two weeks.
  
  
  CONCLUSIONS
  The appearance of a periumbilical hematoma (Cullen's sign) following ultrasound-guided transvaginal oocyte retrieval reflects a retroperitoneal hematoma of a benign course.
