title: Hepatic cavernous hemangiomas: lack of enlargement over time.
abstract: OBJECTIVE
  To determine whether change in size is a characteristic of cavernous hemangioma of the liver.
  
  
  METHODS
  Twenty-one focal masses in 21 patients were diagnosed as cavernous hemangiomas with imaging-guided percutaneous fine-needle biopsy performed between 2 weeks and 2 months after initial imaging study (computed tomography [CT] or ultrasonography [US]). Follow-up imaging examinations (CT, US, or magnetic resonance imaging plus US) were obtained at 5-84 months in all patients.
  
  
  RESULTS
  The cavernous hemangiomas ranged in size from 1.5 to 13.5 cm. At follow-up imaging, 19 (90%) of 21 lesions had not changed in size; the two remaining lesions increased by 1 and 2 cm over 3 and 10 months, respectively.
  
  
  CONCLUSIONS
  The size of the majority of cavernous hemangiomas remains stable for periods of follow-up ranging from 5 to 84 months. Growth of these lesions is not characteristic and, when it occurs, should prompt reassessment of the diagnosis.
