title: An unusual case: bilateral orbital varices.
abstract: OBJECTIVE
  To present a rare case of bilateral orbital varices.
  
  
  METHODS
  An 18-year-old man showing bilateral orbital masses on magnetic resonance (MR) imaging was examined with color Doppler ultrasonography (US), computed tomography (CT) and digital subtraction venography.
  
  
  RESULTS
  The presenting symptoms of the patient were pain and fullness in both orbits induced by bending forward. Ocular examination was normal with the exception of a two millimeter proptosis of both eyes during Valsalva maneuver. MR imaging demonstrated bilateral retrobulbar masses, but was not diagnostic. The comparison of CT images obtained before and after Valsalva maneuver revealed the diagnosis of orbital varices. Color Doppler US and orbital venography demonstrated a large venous connection between the lesions and systemic circulation.
  
  
  CONCLUSIONS
  Clinical presentation of orbital varices is unusual. Different radiological methods may be necessary for the confirmation of the diagnosis and demonstration of the anatomic and the dynamic features of the lesions.
