title: Diagnosis and anatomic mapping of an orbital varix by computed tomographic angiography.
abstract: OBJECTIVE
  To report the use of computed tomographic angiography (CTA) to diagnose an orbital varix.
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  A 73-year-old female was investigated by CTA for carotid artery stenosis. An incidental orbital lesion was discovered. Reformations were obtained.
  
  
  RESULTS
  CTA demonstrated a homogeneously enhancing orbital apex lesion. It provided exceptional anatomic detail of inflow and outflow veins, confirming the diagnosis of an orbital varix.
  
  
  CONCLUSIONS
  CTA is cost effective, fast, non-invasive, and readily available. These aspects combined with the exceptional vascular detail obtained may make CTA the primary test for orbital varix diagnosis.
