title: Clinical and imaging findings in multifocal orbital vascular lesions: a case series.
abstract: BACKGROUND
  A variety vascular disorders can affect the orbit, often manifesting as solitary space-occupying lesions. This study presents a case series of 3 patients with multi-focal orbital vascular conditions emphasizing on the clinical and imaging findings which could assist in the diagnosis and treatment planning.
  
  
  METHODS
  Retrospective consecutive case series of 3 patients with multifocal orbital vascular conditions treated at the Department of Ophthalmology of the University Hospital of Heraklion, in Crete, Greece.
  
  
  RESULTS
  Presenting symptoms included diplopia with compensatory head tilt (1 case) and eyelid protrusion enhanced by Valsalva maneuver (2 cases). MRI and CT studies showed multiple contrast-enhancing vascular lesions, associated with calcifications (1 case). Two lesions were surgically removed, proving to be orbital varices.
  
  
  CONCLUSIONS
  Orbital vascular lesions may present multi-focally and displace adjacent structures. MRI and CT imaging may reveal their multi-focal presence as well as associated features, such as phleboliths.
